This commit includes a hack fix that has allowed
the Ip traffic to work in SA mode. Furthermore,
NSA mode (without the EPC) works in this commit
as well with up to 4 NSA UEs. We will need to
understand better the issue with the UL_DCI
handling in the NRUE that was causing the gNB
to crash.

The AssertFatal in the gNB when the gNB runs out
of downlink HARQ PIDs is caused by the NRUE
receiving a UL_DCI and then building BOTH a UCI
and a CRC/RX pair. So we are essentially sending
a UL and DL DCI to the gNB in this case which
results in an unexpected HARQ PID being received
in the gNB. The filtering in this commit stops
the UCI being built in the NRUE when a UL_DCI
is recevied.

Integrated ra procedure for both nsa and sa.

The IP traffic of a single NRUE works most
of the time in this commit. There seems to
be a bug in the gNB and it will occassionally
crash with a heap-buffer-overflow. This will
be looked at in the next commit.

The changes in this commit include gathering
all of the UCI indications in the queue that
have the same scheduled sfn_slot and sending
them as one aggregated UCI when the scheduled
sfn_slot matches the received ul_tti_request.

MR !1307: WIP: [CI] real time stats and monitoring update
-MR !1280 (closed) : MAC statistics in separate thread
-log X1AP-PDU messages for eNB
-update real time stats collection (from stats logs file instead of stdout)
-update runtime monitoring (conf file, pages)

MR !1301: Fix for blocked process in FR2

MR !1312: CI: adding NSA-B200 sanity check pipeline to automatic regression test-suite
-Validate that all required routes are present 
-Copy the image from a "build" server to a "test" server 
-fixes for the log collection on the CoreNetwork components

MR !1282 : Add MCS from HARQ BLER
-Estimates correct MCS using EMA, kept between target thresholds dl_bler_target_upper and dl_bler_target_lower (conf options) for 1st retx and below dl_rd2_bler_threshold for 2nd retx 
-Maximum MCS configurable 
-on 3rd retx, reduce MCS by 5

Other commits in the integration branch:
-push DL traffic to 60Mb
-solve long ping time in SA

When IP traffic is started on the NRUE, the
gNB immediately crashes
