Subject: [PATCH] Configure watcher tempest's microversion in devstack

Adds a tempest configuration for min and max microversions supported
by watcher. This help us to define the correct range of microversion
to be tested on each stable branch.
New microversion proposals should also increase the default
max_microversion, in order to work with watcher-tempest-plugin
microversion testing.
