Reserve ARFCN dynamically based on BTS band support

Instead of statically specifying a band for a BTS to use, declare a list
of supported bands for each BTS.

At the time of BTS object creation, ask the BTS for band support and try
to dynamically reserve an ARFCN resource which is compatible with any of
the bands supported by the BTS. All this happens transparently to the
test.

Still, the test may want to use a specific band / arfcn. In this case, a
test can use suite.reserve_arfcn(band, arfcn) to reserve a specific
band/arfcn and pass that to the BTS at creation time, which will then
use that one instead of trying to find a suitable one.

It is left as future work to support BTs with multiple TRX, in which
case several arfcn must be reserved. It should not be that difficult,
mostly using "times: X" where X is the amount of trx, changing the API
to use a list of arfcns and the configure() methods of the BTS.
