Harika Punna 6bb0ca2f85 This feature separates the snapshot creation on primary and its backing up on secondary. 
As part of this, a new parameter, which is optional, is added to CreateSnapshotCmd, which seperates the creation and backup.

Syed f46651e672 Support Backup of Snapshots for Managed Storage 
This PR adds an ability to Pass a new parameter, locationType,
    to the “createSnapshot” API command. Depending on the locationType,
    we decide where the snapshot should go in case of managed storage.

    There are two possible values for the locationType param

    1) `Standard`: The standard operation for managed storage is to
    keep the snapshot on the device. For non-managed storage, this will
    be to upload it to secondary storage. This option will be the
    default.

    2) `Archive`: Applicable only to managed storage. This will
    keep the snapshot on the secondary storage. For non-managed
    storage, this will result in an error.

    The reason for implementing this feature is to avoid a single
    point of failure for primary storage. Right now in case of managed
    storage, if the primary storage goes down, there is no easy way
    to recover data as all snapshots are also stored on the primary.
    This features allows us to mitigate that risk.
