Addresses #498
Log messages now look like this when doint a ping via UI (if either the docker socket is not writable or the file path doesn't exist)
socket doesn't exist:

socket is not writable:

Also the frontend dialog for the deployment now shows
deployment error for local socket:

deployment error for nextcloud DSP:

Unfortunately I didn't find a way to get rid of the slightly misleading error message that - in case the socket is not usable - curl will always complain about not being able to connect tho
http://localhost/, even though it's not using any http under the hood but trying to access the UNIX socket directly. When using curl in socket mode (CURLOPT_UNIX_SOCKET_PATH), it will still need somehttp-address for the actualGETcall. See also curl/curl#1338
