tests-1.3: add actions test module

These tests check the behavior of each type of action. The matches used are
exact-match, to satisfy the OXM prerequisites of the set-field actions.
These tests use a single apply-actions instruction.

Only a few action tests have been implemented: push vlan, pop vlan, set vlan
vid/pcp.
