[glusterfind] Test case to verify the glusterfind delete functionality

Verifying the glusterfind delete command functionality with valid
and invalid values for the required and optional parameters.

* Create a volume
* Create a session on the volume
* Perform glusterfind list to check if session is created
* Delete the glusterfind session with the following combinations:
    - Valid values for required parameters
    - Invalid values for required parameters
    - Valid values for optional parameters
    - Invalid values for optional parameters
* Perform glusterfind list to check if session is deleted

    Where:
    Required parameters: volname and sessname
    Optional parameters: debug
