VOL-1558 Implementation of openolt adapter with dep for dependency management
Also updated the build system to take this into account.

Currently dep ensure fails due to missing libraries in voltha-go, but the vendor folder has been updated otherwise.
This can be worked around in development using the LOCAL_VOLTHAGO variable described in the readme
This does not build currrently, but that is due to missing code in voltha-go master.

This pattern is consistent with how voltha-go does things, but does not leave you dependent on it to build.

See the readme for how to use dep.

The resourcemanager file is no longer hidden.
