bugfix for eos shared module and new optimization

This commit address to issues in the eos shard module.  The first one
is a bug fix for returning the running config when the transport is eapi.
The shared module will now return config text instead of an object.  The
second is a optimization that delays when the eos module connects to the
remote devices.  This provies a performance enhancement when using
ssh since the module doesn't default to connecting immediately
