agch: Add VTY queue management configuration
This patch adds the following VTY commands to tune AGCH queue
handling:
agch-queue-management default
agch-queue-management threshold THRES low LOW high HIGH
Examples:
agch-queue-management default
Resets queue management to default parameters.
agch-queue-management threshold 0 low 25 high 75
Start dropping at 25%, drop all messages above 75% queue length
(relative to max queue length corresponding to T3126). Between
low and high, drop with a probability interpolated linearly
between 0 (low) and 1 (high).
agch-queue-management threshold 50 low 0 high 0
Start dropping at 50% and continue until all IMM.ASS.REJ have
been removed from the front (output) of the queue
