[WebUI]Fix Connection Manager stop daemon, return 5 elem from get_host_info()

[ppayne]

Attempting to stop the daemon from Connection Manager in the WebUI would throw an error "An error occurred". On deeper inspection this was because this line threw a ValueError expecting 4 items but only getting 3:

host, port, user, password = host[1:5]

This fix updates the get_host_info() function to also return password.

Tested locally, now successfully stops and starts the daemon from Connection Manager.
