With the removal of traffic_manager we lost this command option, so now
this change makes ATS to respond the rpc call with some basic `TSSystemState`
Information, like intimidation status, draining status, etc.
The output is a simple json output.
Command option is read only, no change is done in the internal ATS state.
Example:
$ traffic_ctl server status | jq
{
"initialized_done": "true",
"is_ssl_handshaking_stopped": "false",
"is_draining": "false",
"is_event_system_shut_down": "false"
}
This also includes some autests to validate the output. Changes to
existing traffic_ctl autest machinery is made to make it simpler to
extend and add more tests.

A clean up on features that makes no more sense to handle using
traffic_ctl(like restart, etc) is also done in this PR. This was implemented when we had traffic_manager.
