/**
 * A utility class that parses a connection string into sections. A Service Bus connection string is a set of key value
 * pairs separated by semi-colon. A typical example is
 * {@code "Endpoint=sb://foo.servicebus.windows.net/;SharedAccessKeyName=someKeyName;SharedAccessKey=someKeyValue"}.
 *
 * 
 * A connection may have the following sections:
 * 

 *     Endpoint, which is mandatory. The hostname part of it is the "Fully qualified namespace".
 *     SharedAccessKeyName and SharedAccessKey, optional, used to authenticate the access to the ServiceBus.
 *     SharedAccessSignature, optional, an alternative way to authenticate the access to the ServiceBus.
 *     EntityPath, optional, the queue name or the topic name under the service namespace
 * 
 *
 * 
 * When you have a ServiceBus connection string, you can use {@link ServiceBusClientBuilder#connectionString(String)}
 * to build a client. If you'd like to use a {@link TokenCredential} to access a Service Bus, you can use this utility
 * class to take the fully qualified namespace and optionally the entity path (queue/topic name) from the connection
 * string and then use {@link ServiceBusClientBuilder#credential(String, TokenCredential)}.
 * 
 *
 * @see ServiceBusClientBuilder#connectionString(String)
