Set custom string in --format

[ritiek]

I see we can set a pre-define format with --format parameter:

$ remoteit connect <device_alias> --format ssh
proxy01.rt3.io -p 10101

It would also be nice to specify any custom format such as:

$ remoteit connect <device_alias> --format "{hostname}:{port}"
proxy01.rt3.io:10101

or such as only display the hostname:

$ remoteit connect <device_alias> --format "{hostname}"
proxy01.rt3.io
