set max_retries to UINT32_MAX for asterisk registrations

After a brief internet outage, I noticed that asterisk had given up
trying to reconnect to my upstream SIP server (looks like the default
value of max_retries is 10).

Although the asterisk "registration" object was disconnected, the
"endpoint" object still reported being up, so the
check_asterisk_endpoints nagios plugin did not alert me to the problem.

This commit sets max_retries to UNIT32_MAX for asterisk registrations by
default. It also adds a new nagios plugin, check_asterisk_registrations.
Unfortunately, the ARI does not expose registrations via the REST API,
so I had to write a hacky bash script to parse the asterisk CLI output.
