Requests the service to start copying an Azure File's contents, properties, and metadata to a new Azure File,
using the specified access conditions, lease ID, request options, and operation context.

@param sourceFile
A <code>CloudFile</code> object that represents the source file to copy.
@param sourceAccessCondition
An {@link AccessCondition} object that represents the access conditions for the source.
@param destinationAccessCondition
An {@link AccessCondition} object that represents the access conditions for the destination.
@param options
A {@link FileRequestOptions} object that specifies any additional options for the request.
Specifying <code>null</code> will use the default request options from the associated
service client ({@link CloudFileClient}).
@param opContext
An {@link OperationContext} object that represents the context for the current operation.
This object is used to track requests to the storage service, and to provide additional
runtime information about the operation.

@return A <code>String</code> which represents the copy ID associated with the copy operation.

@throws StorageException
If a storage service error occurred.
@throws URISyntaxException
