Functions

func CreateValidDiskName 

func CreateValidDiskName(volumeName string) string

Disk name must begin with a letter or number, end with a letter, number or underscore, and may contain only letters, numbers, underscores, periods, or hyphens. See https://docs.microsoft.com/en-us/rest/api/compute/disks/createorupdate#uri-parameters

Snapshot name must begin with a letter or number, end with a letter, number or underscore, and may contain only letters, numbers, underscores, periods, or hyphens. See https://docs.microsoft.com/en-us/rest/api/compute/snapshots/createorupdate#uri-parameters

Since the naming rule of disk is same with snapshot's, here we use the same function to handle disks and snapshots.

Return `MaxEntries` snapshots from zero. 3. StartingToken is not null, and MaxEntries is null. Return all snapshots from `StartingToken`. 4. StartingToken is not null, and MaxEntries is not null. Return `MaxEntries` snapshots from `StartingToken`.
