CFRA procedure is working! But gNB still crashes

How? Well, we had to properly allocate the
ul_config_req. We also had to update the
ue_get_rach function. There were several
places where the functionality would check
for a particular mode (ra, sa, phy_test, etc).
In some of these places we had to add NSA mode.
In the VNF, they start the scheduler after 3 sec,
this is sort of a hack, might want to revisit.
This commit also includes removal of printfs.
