Refactoring and cleaning up

Cluster management pb fix (#372)

* downgrade lager because of logging problems
* change test setup

- forking ct_slave because it cannot be configured as I want it to
- now sets the working directory for slaves, so lager logs to the
correct directory
- standard output of slaves is written to the ct-log and to stio.log
file, which should make debugging easier
- protocol buffer process now also reports stacktrace to client
* also testing connect_to_dcs
* use different node names for cluster management test
* Adapted to cleanup of antidote_pc_codec
* Upgraded to lint v0.1.10 which is checking more things.
* Few fixes for the connection descriptors
* Encoding ignore in pb_client
* Updating the dependencies
