Hello,

with MI code planned to be removed, I updated the kamctl and default kamailio.cfg to use jsonrpcs (jsonrpc server) module instead of mi_fifo to interact with kamailio at runtime.

The default fifo file for rpc command is /var/run/kamailio/kamailio_rpc.fifo and expects JSONRPC commands as described at:

- http://kamailio.org/docs/modules/devel/modules/jsonrpcs.html#idp31525708

Switching back to mi_fifo is still possible by loading the module and editing kamctlrc, but the module might not make it to 5.0, so for new installations and testing is better not to use it.

Few rpc commands are missing in carrierroute, otherwise the kamctl commands should work just as before, but be aware that the output is now in json format.

Testing of the master branch with the latest kamctl and providing feedback will be really appreciated -- I could do tests only for the modules I typically use.

Cheers, Daniel
