Issue with global configuration parameters in hpe.conf, if updated in multiple backend then it damage plugin operations

[virendra-sharma]

Observation: -

1. Volume mount failing with timeout error, please find error below.
2. It is observed that after mount failure, volume, snapshot & clone creation also fails intermittently.
3. In case volume mount pass, it will fail to mount it's snap volume.
4. Failure error of mount says "volume name must be unique", it is inappropriate error message.

Steps: -

1. create block volume and mount it.
2. create snapshot of volume and mount snapshot.
3. create clone of volume and mount it.

Error: -

Mount error : "docker: Error response from daemon: create volume1: found reference to volume 'volume1' in driver 'hpe:latest', but got an error while checking the driver: error while checking if volume "volume1" exists in driver "hpe:latest": Post http://%2Frun%2Fdocker%2Fplugins%2Fa7b2a1f89860c5314c4229f14aff62787f79547ff23cc0922b386ce09b1f0f57%2Fhpe.sock/VolumeDriver.Get: net/http: request canceled (Client.Timeout exceeded while awaiting headers): volume name must be unique."

@imran-ansari any update on this ?

[prablr79]

needs quick investigation

CI issue resolved after updating "3PAR_DEBUG=True" in default backend and keep false in all other backends. But still just updating parameter should not affect plugin behavior.

Also, Error message updated in above issue looks misleading, it will be good if we look into it as well.
