Use tailored sample rate only use for 6, 50 and 75 PRB. For all other bandwidths,
we use the full LTE rate and downsample.
With 5.76e6 as base sample rate, for example, we had some issue during the tests like:
[zmq] Error: tx time is 0.178 ms in the past (7833600 < 7835648)
[zmq] Error: tx time is 0.011 ms in the past (7835520 < 7835648)
Using a higher sample rate seems to work better.

It turned out that the Amarisoft and SRS eNB scheduler produces
slightly different maximum data rates for both UL and DL.

specifiying the rx/tx_freq for the eNB is optional. But when
it's done it needs to be correct. There seems to be an issue
when mapping the freq[0-3] between srsENB and Amarisoft eNB.
So it's safe to just drop the config here altogether.

we need to make the rf_port a param in the cell list because for CA with
two cells on different EARFNCs, the RF port is different
for two cells without CA on the same EARFCN the RF port is the same
so we need to be able to configure it

This way we get rid of object related content in resource.py and we can
finally move it to core/ in next commit.

This way we benefit from:
* knowing which attributes are used/required by each object class and
subclass
* Having validation function definitions near the class going to use them

this patch moves the rf_dev_args creation for both eNB types
into the eNB base class, since they are identical.
the patch also fixes the arguments for all CA and MIMO configurations

Two implementations are provided:
* Amarisoft Ctrl interface (websocket)
* Mini-Circuits Programmable Attenuator (HW, HTTP API) [1]
in Amarisoft ENBs, if no rfemu is configured explicitly, the Ctrl
interface one is used by default, while still being possible to use the
HW one.

this allows to optionally specify a the GTP bind_address for a enb object
in the resources.conf
this address is then used for binding the listening socket for gtp connections
which, in turn, allows to run the enb and epc on the same host.
when gtp_bind_addr is not specified, addr is used by default
this is especially useful if eNB and EPC run on the same host
and ZMQ is used for RF between eNB and UE. Two eNB addresses
are needed in this case, one bind address and one "remote-accessable"
address for the UEs ZMQ radio to connect to
