Great work Malcolm!
This is looking good. One thing that I was discussing with @rohit-nayak-ps is that we should make sure to ignore ghost schema changes from these validations.
However, there are a few other places we need to update before fully adopting those conventions (e.g VDiff should ignore tables that are related to ghost).
We can work on that as separate PR.
Does this mean that in the presence of gh-ost artifact tables workflow creation will always fail (with the changes in this PR)? |

As a follow-up, I think it would be great to add the VSchema validation to ValidateSchemaKeyspace as well

Description
This PR adds in vschema validation during creation of a ReshardWorkflow. If any of the source shards have tables in their
_vtdatabase that are not in the vschema then the creation of the ReshardWorkflow will fail. We will then return which shards failed their vschema checks and what tables caused their respective failures.Related Issue(s)
