Added 'Open Karaf console' feature

[kubawolanin]

This was a feature request from Peder Schmedling on Twitter - https://twitter.com/Leif_/status/931479506824544256

The PR might be a little bit related to #9.
It introduces a new configuration setting - openhab.karafCommand.

By default its value is ssh openhab@%openhabhost% -p 8101
%openhabhost% is effectively replaced with the openhab.host value.

Pressing Ctrl + Shift + P and choosing "openHAB: Open Karaf console" the command will execute in a new Terminal window (default one) integrated with VSCode.

In my personal setup my default terminal is Git Bash:

"terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe",

Note that you need to:

• have ssh installed on your environment
• have Karaf exposed to the external interface

This feature allows you to modify the new param and e.g. show the openHAB logs immediately:

    "openhab.karafCommand": "ssh openhab@%openhabhost% -p 8101 -t 'log:tail'",
