podman-remote.conf enablement

add the ability for the podman remote client to use a configuration file
which describes its connections. users can now define a connection the
configuration and then call it by name like:

podman-remote -c connection1

and the destination and user will be derived from the configuration
file.  if no -c is provided, we look for a connection in the
configuration file designated as 'default'.  If the configuration file
has only one connection, it will be deemed the 'default'.
