Fixed coverage test/travis
Adding console application that will cover configuration for:
* Users
* Groups
* SMPP client connectors
* Routings
jcli is able to connect and disconnect from router and smppcm backends
work on jcli's connect/disconnect
Changed jcli to be a telnet server (using conch):
* Easier security implementation (in future)
* reactor-ready
No more needing cmd2 module
Added managers in jcli for managing:
* users
* groups
* router
* smppcm
* jcli is started as jasmin service
* implemented a part of SMPP Client management api through jcli, remaining calls: show, update, stop, start
