Wait for server activations for the updated servers

In test_list_servers_by_changes_since, Tempest tries to get a server
list with changes-since parameter. The test expects we can get all
servers with the parameter, but sometimes we could not get it and the
gate tests failed.
On "create a server" API Nova creates a DB record of the server as
the first step, then updates the record by each step(scheduling,
networking, etc.) during the server creation. If the test runs just
after the DB record creation, the record is not updated and "get a
server list" API with changes-since parameter does not contain the
server. As the result, the test fails.

This patch makes the test wait for server activations to avoid the
non-updated servers.
