Fix Retries for Policies

This applies changes to make retries work properly
for all control loops. The current design was ignoring
the upper bound of the retries and retrying until either
a success or control loop timeout occured. This is now
fixed to only do retries until the limit is reached that
is specified from the policy.

The operation is now started in the GUARD.PERMITTED rule.
I think this is better because it stops Policy from doing
extra processing if there is a guard deny. This is also
needed so that we can properly do retries for all cases.

The notifications sent in GUARD_NOT_YET_QUERIED and
GUARD.RESPONSE are now more informative with the
message specifying the actor and recipe. The not queried
rule has a message stating that we are sending a query
to guard and the guard response message in the guard
response rule specifices the result from guard.

During a retest of vDNS it appeared that the archetype
template was no longer working, this was because there
were changes in the JUnit template that were not
reflected in the archetype template. These were added
to archetype and vDNS is verified to work again.

Another small fix needed was making sure the action for
vCPE is "Restart" instead of "restart". APPC will
reject our request if "Restart" is not sent as the
action.
