Drop test for lower constraints

As we agreed, drop lower constraints test from stable branches to avoid
difficulty of maintaining package depencencies for the recent pip
dependency resolver.

This update also includes a change in master branch to fix gate tests.

* Update SQL statement for update mysql to 8.0 in which allowed no
  implicit user creation [1].

* Remove using `jsonutils.dump_as_bytes()` for a file object which is
  deprecated usage and failed with `ValueError: Circular reference
  detected` [2].
