There is a new function used in keactrl tests which waits for the server
to shutdown, rather than check if it is down already. This is to avoid
race condition when the process may not completely terminate when we
check that it is.

- Renamed kea4 and kea6 parameters to dhcp4 and dhcp6
- Location of the kea binaries is specified in the keactrl.conf
- Swap pools and subnets in kea.conf.
- Renamed keactrl commit command to reload
- Added -s and -c command line options.

Also, a few corrections in Makefiles.
