GID range parameter change requires pod restart

[RomanBednar]

/kind bug

What happened?
In order to effectively change gidRangeStart and gidRangeEnd values defined in StorageClass the EFS controller pod currently requires a restart.

This is because the driver maintains one GID cache per fileSystemId. It's initialized when the first volume is provisioned from a StorageClass. All subsequent volumes are provisioned with the GID range specified in the StorageClass that was used first.

The driver should support updating the ranges and generate GID from the range provided in each CreateVolume call, not from the first one.

What you expected to happen?
gidRangeStart and gidRangeEnd values should be effectively applied when changed in the StorageClass without the need to delete or restart any controller pods.

How to reproduce it (as minimally and precisely as possible)?

1. Create SC without GID range parameters
2. Dynamically provision a new PV
3. Check that the volume gets GID of 50000 (default for gidRangeStart)
4. Add a gidRangeStart parameter to exiting SC with any custom value other than 50000
5. Dynamically provision another PV
6. Check that the new volume got GID of 50001 and the custom value got ignored

Anything else we need to know?:

Environment

• Kubernetes version (use kubectl version):
• Driver version: v1.3.8
