zebra: lsp_install() failed due to ZEBRA_FLAG_SELECTED check
ZEBRA_FLAG_SELECTED hasn't been set yet by the time lsp_install is
called. The call path is:
rib_process -> rib_process_add_fib -> zebra_mpls_lsp_install -> lsp_install
but ZEBRA_FLAG_SELECTED is set in rib_process after it calls
rib_process_add_fib. I can't think of anything that it would hurt to
install the LSP regardless of whether ZEBRA_FLAG_SELECTED is set later.
I also cleaned up some UI (json and display the pretty label names
instead of their numeric values).

pimd: Fix WG/SGRpt & WG J/P processing
During processing of Join/Prune,
for a S,G entry, current state is SGRpt, when only *,G is
received, need to clear SGRpt and add/inherit the *,G OIF to S,G so
it can forward traffic to downstream where *,G is received.
Upon receiving SGRpt prune remove the inherited *,G OIF.
From, downstream router received *,G Prune along with SGRpt
prune. Avoid sending *,G and SGRpt Prune together.
Reset upstream_del reset ifchannel to NULL.
Testing Done:
Run failed smoke test of sending data packets, trigger SPT switchover,
*,G path received SGRpt later data traffic stopped S,G ages out from LHR, sends only
*,G join to upstream, verified S,G entry inherit the OIF.
Upon receiving SGRpt deletes inherited oif and retains in SGRpt state.

pimd: fix channel_oil and upstream RPF in sync
During PIM Neighbor change/UP event, pim_scan_oil api
scans all channel oil to see any rpf impacted. Instead of
passing current upstream's RPF it passes current RPF as 0 and
does query to rib for nexhtop (without ECMP/Rebalance). This creates
inconsist RPF between Upstream and Channel oil.
In Channel Oil keep backward pointer to upstream DB and fetch up's
RPF and passed to channel_oil scan.
Decrement channel_oil ref_count in upstream_del when decrementing
up ref_count and it is not the last.
Created ECMP based FIB lookup API.
Testing Done:
Performed following testing on tester setup:
5 x LHR, 4 x MSDP Spines, 6 Sources each sending to 1023 groups from one of the spines.
Total send rate 8Mpps.
Test that caused problems was to reboot every device at the same time.
After fix performed 5 iterations of reboot devices and show no sign of the problem.
