Removing voltha namespace from bbsim address and skip timeouts

[Namespace]
As long as VOLTHA and BBSim are in the same namespace is not required
to specify it. This change allow different deployment setups.

[Timeouts]
BBSim runs much faster than real hardware so the timeout shouldn't be
required.
