Subject: Use explicit versioning in MetadataShardDataTreeSnapshot
X-Git-Tag: release/magnesium~74
X-Git-Url: https://git.opendaylight.org/gerrit/gitweb?p=controller.git;a=commitdiff_plain;h=669a2b1087c9e793cb85ddf173f2c84840d05387

Use explicit versioning in MetadataShardDataTreeSnapshot

Rather than relying on the default version, make sure we use
whatever the version is defined for the message at hand.

JIRA: CONTROLLER-1919
Change-Id: Ic325ba93e5152570586f7a0baa8ce2abf8053c4e
