Avi Kivity a203c87f0d Merge "Disallow mixed schemas" fro Paweł
"This series makes sure that schemas containing both counter and non-counter
regular or static columns are not allowed."

* 'pdziepak/disallow-mixed-schemas/v1' of github.com:cloudius-systems/seastar-dev:
  schema: verify that there are no both counter and non-counter columns
  test/mutation_source: specify whether to generate counter mutations
  tests/canonical_mutation: don't try to upgrade incompatible schemas

(cherry picked from commit 9e4ae0763d)
