What does this PR do / why do we need this PR?

Changed the default objectStorage.sync.destinationType to azure, for azure clusters. Having this default to s3 caused issues with network policies / update-ips for clusters that are only using azure storage.

Information to reviewers

Init and migration script tested, but I have not re-tested using destinationType as azure.
