nimble storage: retype support
retype support between 2 nimble backends with and without migration - update the provider location for fetching the correct discovery ip for volume discovery - prevent failures on snap deletetion / offline as they could already be in those states Change-Id: If21bd6c6aa9cef45f57f32034e26502cd02743b2 Closes-Bug: #1790907 Signed-off-by: Raunak Kumar <rkumar@nimblestorage.com>
