openbsd_pkg: add upgrade argument.

Running the module with the argument "upgrade=yes" invokes an upgrade of

Functionality requested by @qbit.
Refactor openbsd package upgrade change to work more like yum/apt
Simplify logic by using required=True.
openbsd_pkg: revert "changed" simplification.

module.exit_json() does not like when the "changed" variable contains a
match object:

TypeError: <_sre.SRE_Match object at 0x81e2ae58> is not JSON serializable

mysql_replication should not connect to the 'mysql' database

opkg: fix package state detection
composer: Fix `changed` status that always returns False

re.match in has_changed function never worked properly, because match
requires searched sequence to be present exactly at a start of processed
string, which is not the case here.
