ADF cmdlet changes

[yitao-zhang]

1. Base cmdlet type switch to use Profile:
   This is to fix the regression in new subscription registration with RP that we discussed a couple of weeks ago with Mark.
2. New-AzureDataFactoryEncryptedValue cmdlet supporting M data sources.
   This adds a couple of new parameters to support the new M data sources: MySQL, Teradata, etc.
