[F.REQ] Added ability to connect to different docker engines

[alex-agency]

Currently, application using docker unix socket for connection to docker daemon on the same docker host. It doesn't allow connection to different docker hosts and you can manage containers only inside same docker host.

The main reason to add ability to setup tcp socket, which allows connect to any docker engine and install this app wherever you want.

Please refer to https://docs.docker.com/engine/reference/commandline/daemon/
-H, --host=[] Daemon socket(s) to connect to.

from doc

If you need to access the Docker daemon remotely, you need to enable the tcp Socket. Beware that the default setup provides un-encrypted and un-authenticated direct access to the Docker daemon - and should be secured either using the built in HTTPS encrypted socket, or by putting a secure web proxy in front of it. You can listen on port 2375 on all network interfaces with -H tcp://0.0.0.0:2375, or on a particular network interface using its IP address: -H tcp://192.168.59.103:2375. It is conventional to use port 2375 for un-encrypted, and port 2376 for encrypted communication with the daemon.
