Implement TLS API Support

* Added flags to point to TLS PEM files to use for exposing and connecting
  to an encrypted remote API socket with server and client authentication.
* Added TLS fields for system connection ls templates.
* Added special "tls" format for system connection ls to list TLS fields
  in human-readable table format.
* Updated remote integration and system tests to allow specifying a
  "transport" to run the full suite against a unix, tcp, tls, or mtls
  system service.
* Added system tests to verify basic operation of unix, tcp, tls, and mtls
  services, clients, and connections.
