VTY: make target uplink Rx level VTY-configurable 

We used to have -75 dBm as the target value for the uplink receive
level.  Now this is configurable.

The parameter is used as input into the power control loop that adjusts
the MS transmit power in order to achieve the target rx value on the
BTS Rx input.
