THRIFT-211. erlang: Allow clients to be created without connecting

Add a client option to prevent the initial connect (which causes
the protocol factory to be ignored).  The main use case for this
is testing the proper handling of clients that cannot connect.
Update the tether test to use this feature instead of a raw
gen_server:start call.
