The normal flag was enabling detail messages, but what we want is the
detail flag enabling normal messages.
Remove the _ONLY macro while at it, it's only used for config print &

Problem Statement:
=================
PIM Logs are coming at interval of 1 minute although pim
is not enabled.
Root Cause Analysis:
====================
By default, RCPM configures the PIM debugs when router comes up
via script. The product cannot disable PIM even though it is not required.
Hence moving these logs under a new debug option which will not be
enabled by default.
Fix:
====
Added a new option "detail" in the cli:
debug pim nht detail

when ever a FRR Client wants to send any data to another node
using MLAG Channel, uses below mechanisam.
1. sends a MLAG Registration to zebra with interested messages that
it is intended to receive from peer.
2. In response to this request, Zebra opens communication channel with
MLAG. and also in Rx. diretion zebra forwards only those messages which
client shown interest during registration
3. when client is no-longer interested in communicating with MLAG, client
posts De-register to Zebra
4. if this is the last client which is interested for MLAG Communication,
zebra closes the channel.
why PIM Needs MLAG Communication
================================
1. In general on LAN Networks elecetd DR will send the Join towards
Multicast RP in case of a LHR and Register in case of FHR.
2. But in case DR Goes down, traffic will be re-converged only after
the New DR is elected, but this can take time based on Hold Timer to
detect the DR down.
3. this can be optimised by using MLAG Mecganisam.
4. and also Traffic can be forwarded more efficiently by knowing the cost
towards RP using MLAG

Original Idea is to display normal & detailed debugs when detailed
debug alone is configured. because of this "sh debugs" are showing
wrong Information, because same macro is used to disply the configured
debugs.
that means even if Normal debug is configured, detailed macro returns
TRUE. To avoid this ambiguity check whetehr detailed debug is configured
or not during dumping configured debugs. In all other places using
old macro.

Issue: Configure "ip pim rp x.x.x.x 225.0.0.0/4".
Show running config shows "ip pim rp x.x.x.x 224.0.0.0/4"
This is mis-leading.
Root-cause: Internally 225.0.0.0/4 is getting converted to
224.0.0.0/4 group mask, since the prefix length is 4.
Fix: Restrict the user to configure inconsistent group address
mask by throughing a cli error "Inconsistent address and mask".
