tests: use correct key for deleting entry.
OSPF mixes uses of "delete" and "del_action" depending on which library
function is called. It's a bug-prone mess that needs fixing; however, for
now we fix the one obvious incorrect use in this test.
ospf6d: External LSAs reoriginates on every redistribute CLI
Problem Statement:
==================
Everytime redistribute CLI is executed, external LSAs are
re-originated. When there is no change in the CLI parameters
the LSAs should not get re-originated.
Fix:
=================
Check if the CLI params are same, do not re-originate the LSA.

- In order to run tests in parallel the netns-based vrfs need to

pimd: change ranges to 1..max, type align with IETF YANG.
While defaults are good picks for "reasonable" guesses, min and max
range values really aren't. Operators and experimenters often like to
configure "unreasonable" values to stress test, tests boundary
conditions and explore innovations.
With that in mind, change all ranges to 1..max (of type).
While we're here add optional ignored values in the "no" CLI forms.

bgpd: imported evpn rt5 routes copy igpmetric
when doing BGP over an IGP platform, the expectation is that
the path calculation for a given prefix takes into account the
igpmetric given by IGP.
This is true with prefixes obtained in a given BGP instance where
peering occurs. For instance, ipv4 unicast entries or l2vpn evpn
entries work this way. The igpmetric is obtained through nexthop
tracking, like below:
however, for imported EVPN RT5 entries, the igpmetric was not
copied from the parent path info. Fix it. In this way, the
imported route entries use the igpmetric of the parent pi.

ospfd: Summarised External LSA is not flushed in one scenario
Fix CI Failure test_ospf_type5_summary_tc45_p0
Problem Statement:
==================
Summarised LSA is not flushed in OSPFv2 in below scenario:
1. Configure summary-address in ospfv2
2. redistribute static and connected.
3. Check the LSAs are received on neighbor.
4. Now remove all OSPFv2 configs, so neighbor will still have the summarised LSA.
5. Configure router ospf with redistribute static and connected.
6. Check the DB, summarised LSA is present although the configuration is not present.
7. Now configure the summary-address and remove the configuration after sometime.
8. The summarised LSA will be still present.
RCA:
==================
When self originated LSA is received from the neighbor and that
LSA is summarised one, the LSA is refreshed but a flag is not set
due to which it was not able to remove it later.
Fix:
==================
Set the originated flag when refreshing summarised LSA.

bgpd: Limit processing to what is needed in rpki validation
The processing was looping over all bgp instances then
over all peers then over all safi's to find a match
for a prefix received in order to validate it.
Suppose you have 100 peers each sending you the same
prefix. This code will cause it to look at each node 100
times since we look at for each peer. This is especially
egregarious because we never ever do anything with the peer
when we are looping over them.
Remove the peer loop, significantly reduce processing.

To separate words, use underscores (_). For example, tests/topotests/bgp_new_example.

Regular and no-form commands should be defined separately to fix this.
