Description
-------

This patch adds a test for the PJSIP keep_alive_interval option. It sets the keep_alive_interval to 2 seconds, makes a TCP client connection to the PJSIP stack, and then waits for 5 keep alives. Upon receiving 5 packets, it disconnects and stops the test.

In all cases, the test verifies on stopping:
* That 5 total packets were received
* That the time deltas between packets were received within approximately 2 seconds of each other
* That the keep alive values are all '\r\n\r\n'

Note that this test is being written for two reasons:
(1) Because tests are good
(2) So that the revision that added the keep_alive_interval option can be backported to Asterisk 13. As it turns out, having keep alives for connection oriented transports is super useful under certain non-ideal yet depressingly common network conditions.
