Let Stasis load itself with default values

While a Stasis configuration file is nice, it shouldn't be mandatory.
We can carry on with default values.

Fix some bugs in CDRs; add some CLI commands to help debugging

This patch fixes a few minor bugs and one major one: the CDR by bridge
container was less than helpful. The mechanism previously used to try
and find all of the CDRs in a particular bridge ended up missing CDRs,
resulting in incorrect records.

When looking up CDRs in a bridge, we now just bite the bullet and do
a selection across all existing CDRs.

Move when bridge channel enter is published so it does not interrupt the thought of some lines of code.
