102   get_connection_type
103       This method tries to guess the right connection type for the task and
104       returns it.
105
106       Current return values are below:
107
108       ·   SSH: connect to the remote server using Net::SSH2
109
110       ·   OpenSSH: connect to the remote server using Net::OpenSSH
111
112       ·   Local: runs locally (without any connections)
113
114       ·   HTTP: uses experimental HTTP connection
115
