/**
 * V2 APIs for creating, updating, or deleting individual components in a collection's schema.
 *
 * This API (POST /v2/collections/collectionName/schema {...}) is analogous to the commands
 * supported by the v1 POST /collectionName/schema API.
 *
 * 
Typically v2 "POST" API implementations separate each "command" into a different method. This
 * is not done here because the v1 API code in SchemaHandler expects to consume the request body
 * itself (meaning that nothing _before_ SchemaHandler can consume the request body).
 *
 * As a result the single method below handles all "commands" supported by the POST /schema API:
 * 'add-field', 'delete-field', 'replace-field', 'add-dynamic-field', 'delete-dynamic-field',
 * 'replace-dynamic-field', 'add-field-type', 'delete-field-type', 'replace-field-type',
 * 'add-copy-field', and 'delete-copy-field'.
