public class CreateVolumeAction {
    /**
     * Creates an EBS volume that can be attached to an instance in the same Availability Zone.
     * Note: The volume is created in the regional endpoint that you send the HTTP request to. For more information see
     * Regions and Endpoints. You can create a new empty volume or restore a volume from an EBS snapshot. Any AWS
     * Marketplace product codes from the snapshot are propagated to the volume. You can create encrypted volumes with
     * the Encrypted parameter. Encrypted volumes may only be attached to instances that support Amazon EBS encryption.
     * Volumes that are created from encrypted snapshots are also automatically encrypted. For more information, see
     * Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide. For more information, see Creating or
     * Restoring an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.
     *
     * @param endpoint         Optional - Endpoint to which request will be sent.
     *                         Default: "https://ec2.amazonaws.com"
     * @param identity         ID of the secret access key associated with your Amazon AWS or IAM account.
     *                         Example: "AKIAIOSFODNN7EXAMPLE"
     * @param credential       Secret access key associated with your Amazon AWS or IAM account.
     *                         Example: "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
     * @param proxyHost        Optional - proxy server used to connect to Amazon API. If empty no proxy will be used.
     *                         Default: ""
     * @param proxyPort        Optional - proxy server port. You must either specify values for both proxyHost and
     *                         proxyPort inputs or leave them both empty.
     *                         Default: ""
     * @param proxyUsername    Optional - proxy server user name.
     *                         Default: ""
     * @param proxyPassword    Optional - proxy server password associated with the proxyUsername input value.
     *                         Default: ""
     * @param headers          Optional - string containing the headers to use for the request separated by new line (CRLF).
     *                         The header name-value pair will be separated by ":".
     *                         Format: Conforming with HTTP standard for headers (RFC 2616)
     *                         Examples: "Accept:text/plain"
     *                         Default: ""
     * @param queryParams      Optional - string containing query parameters that will be appended to the URL. The names
     *                         and the values must not be URL encoded because if they are encoded then a double encoded
     *                         will occur. The separator between name-value pairs is "&" symbol. The query name will be
     *                         separated from query value by "=".
     *                         Examples: "parameterName1=parameterValue1¶meterName2=parameterValue2"
     *                         Default: ""
     * @param version          Optional - Version of the web service to made the call against it.
     *                         Example: "2016-11-15"
     *                         Default: "2016-11-15"
     * @param availabilityZone Specifies the Availability Zone in which to create the volume. See more on:
     *                         https://aws.amazon.com/about-aws/global-infrastructure
     * @param encrypted        Optional - Specifies whether the volume should be encrypted. Encrypted Amazon EBS volumes
     *                         may only be attached to instances that support Amazon EBS encryption. Volumes that are created
     *                         from encrypted snapshots are automatically encrypted. There is no way to create an encrypted
     *                         volume from an unencrypted snapshot or vice versa. If your AMI uses encrypted volumes, you
     *                         can only launch it on supported instance types. For more information, see Amazon EBS
     *                         Encryption in the Amazon Elastic Compute Cloud User Guide - Valid values: "false", "true"
     *                         Any other but valid values provided will be treated as "false"
     *                         Default: "false"
     * @param iops             Optional - Only valid for Provisioned IOPS SSD volumes. The number of I/O operations per
     *                         second (IOPS) to provision for the volume, with a maximum ratio of 30 IOPS/GiB.
     *                         Constraint: range is 100 to 20000 for Provisioned IOPS SSD volumes.
     * @param kmsKeyId         Optional - The full IAM_INSTANCE_PROFILE_ARN of the AWS Key Management Service (AWS KMS)
     *                         customer master key (CMK) to use when creating the encrypted volume. This parameter is only
     *                         required if you want to use a non-default CMK; if this parameter is not specified, the default
     *                         CMK for EBS is used. The IAM_INSTANCE_PROFILE_ARN contains the arn:aws:kms namespace, followed
     *                         by the region of the CMK, the AWS account ID of the CMK owner, the key namespace, and then
     *                         the CMK ID.
     *                         Note: If a KmsKeyId is specified, the encrypted input must be set on "true".
     *                         Example: "arn:aws:kms:us-east-1:012345678910:key/abcd1234-a123-456a-a12b-a123b4cd56ef"
     * @param size             Optional - size of the volume, in GiBs. If you specify a snapshot, the volume size must be
     *                         equal to or larger than the snapshot size. If you're creating the volume from a snapshot
     *                         and don't specify a volume size, the default is the snapshot size.
     *                         Constraints: 1-16384 for "gp2", 4-16384 for "io1", 500-16384 for "st1", 500-16384 for "sc1",
     *                         and 1-1024 for "standard".
     * @param snapshotId       Optional - Snapshot from which to create the volume
     *                         Default: ""
     * @param volumeType       Optional - Volume type of the Amazon EBS volume - Valid values: "gp2" (for General
     *                         Purpose SSD volumes), "io1" (for Provisioned IOPS SSD volumes), "st1" (for Throughput
     *                         Optimized HDD), "sc1" (for Cold HDD) and "standard" (for Magnetic volumes).
     *                         Default: "standard"
     * @return A map with strings as keys and strings as values that contains: outcome of the action, returnCode of the
     *         operation, or failure message and the exception if there is one
