[maven-release-plugin] prepare for next development iteration
Add the ability to specify a HELIOS_MASTER environment variable

It will tell the CLI where to talk to to reach a helios cluster.
It can either be http://location_of_master:port or site://sitename.
If a destination is specified on the commandline, it overrides the
environment variable.
TemporaryJobs no longer throws an exception if it encounters a directory

There shouldn't be any directories in the temp directory, but if we
should just ignore it if one is there. Also, TemporaryJobsTest now
creates it's own directory under the main temporary directory so
that is not effected by other tests using the temp directory.
test: fix helios zk failover test spurious failure

ZooKeeperHeliosFailoverTest.verifyCanDeployWithOneNodeDeadAfterOneNodeDataLoss
was racy and could end up with just one single intact node, one node
down and one node without any data. The ZK quorum would then be broken,
and it's not fair to expect to be able to make progress beyond that
point.

HELIOS_HOST_FILTER was being ignored by TemporaryJobs

When choosing which host(s) to deploy to, TemporaryJobs
would use HELIOS_HOST_FILTER to come up with a list of
hosts matching the filter. But when it came time to deploy,
it would ignore this list, and use the list of all hosts
instead, effectively deploying to a random host.
