Fully utilize the northbound to hold pointers to our private data
instead of searching for data structures every time we need to change a
configuration.
Highlights:
* Support multiple mesh groups per PIM instance (instead of one)
* Use DEFPY instead of DEFUN to reduce code complexity
* Use northbound private pointers to store data structures
* Reduce callback names size

VRF creation can happen from either cli or from
knowledged about the vrf learned from zebra.
In the case where we learn about the vrf from
the cli, the vrf id is UNKNOWN. Upon actual
creation of the vrf, lib/vrf.c touches up the vrf_id
and calls pim_vrf_enable to turn it on properly.
At this point in time we have a pim->vrf_id of
UNKNOWN and the vrf->vrf_id of the right value.
There is no point in duplicating this data. So just
remove all pim->vrf_id and use the vrf->vrf_id instead
since we keep a copy of the pim->vrf pointer.
This will remove some crashes where we expect the
pim->vrf_id to be usable and it's not.

Problem reported that when certain pim commands were entered, they
showed up duplicated in the configuration both under default instance
and every vrf (whether pim was used there or not.) This was because
these particular parameters are global only and the function doing
the display would repeat for each vrf. This fix only displays those
in the default case (and removes them from the help for entering
under a vrf.)

Just some cleanup before I touch this code; switching to typesafe list
macros & putting the data directly inline.

Issue:
User is allowed to configure only hello without hold timer but when undo
config, the hold timer is mandatory as shown below:
FRR-4(config-if)# ip pim hello 10
<cr>
(1-180) Time in seconds for Hold Interval
FRR-4(config-if)# ip pim hello 10
FRR-4(config-if)# no ip pim hello 10
(1-180) Time in seconds for Hold Interval
FRR-4(config-if)# no ip pim hello 10
% Command incomplete: no ip pim hello 20
Fix:
Making the hold timer as optional when undo config.

Also included display of hold time in CLI 'show ip pim int <intf>' cmd
and json commands.
Issue:
PIM neighbor not coming up if hold time is less than hello timer
since hello is sent every 4 sec and hold is 1 sec,
because of this nbr is flapping
Fix:
Do not allow configuration of hold timer less than hello timer
Also reset the value of hold timer to 3.5 times to hello whenever
only hello is modified so that the relationship holds good.

This command has been added in the context of

originating RP, it will drop the message.
