* smoketest: T6747: call wait after commit() only for FRR related tests
Commit 702a60a8de28 ("smoketest: T6746: wait after commit() until frr-reload
is no longer running") added a guard timeout for every commit executed via CLI
smoketests. This commit changes the bahavior to only add the guard timeout
for FRR related testscases.
This improves the overall smoketest time.
* configd: T6747: use one long-lived instance of FRRender
Previously there was one FRRender() instance per config session. This resulted
in re-rendering the FRR configuration every time a new config session was
created.
Example:
vyos@vyos:~$ configure
vyos@vyos# set interfaces dummy dum0 description foo
vyos@vyos# commit
vyos@vyos# exit
vyos@vyos:~$ configure
vyos@vyos# set interfaces dummy dum0 description bar
vyos@vyos# commit
vyos@vyos# exit
In the past this caused a re-render of the FRR configuration as the delta check
added in commit ec80c75d6776 ("frrender: T6746: only re-render FRR config if
config_dict did change") evaluated to false, as it operated on a new instance
of the FRRender class.
With this change there is no FRR re-render, as there is nothing to update
in FRR.

* smoketest: T6746: add substring search in getFRRconfig()
Some daemons (e.g. bgpd) have several nested substrings/sections like
router bgp 100
address-family ipv4 unicast
..
exit-address-family
exit
We can now use getFRRconfig() with the substring option to extract only
address-family ipv4 unicast
..
exit-address-family
Making config validation more granular
* frrender: T6746: only re-render FRR config if config_dict did change
* frrender: T6746: fix naming glitch isis/eigrp
* frrender: T6746: add --stdout option when running with debug flags
* smoketest: T6746: remove unneeded commit_guard time
It was an invalid workarround as the underlaying issue seems to be a race
condition in CStore.
The commit process is not finished until all pending files from
VYATTA_CHANGES_ONLY_DIR are copied to VYATTA_ACTIVE_CONFIGURATION_DIR. This is
done inside libvyatta-cfg1 and the FUSE UnionFS part. On large non-interactive
commits FUSE UnionFS might not replicate the real state in time, leading to
errors when querying the working and effective configuration.

Do not use custom daemon definitions like bgpd - re-use them from e.g.
vyos.frrender.bgp_daemon

We need to ensure when stressing FRR with the smoketests that no unexpected
crash happens. We simply verify the PID of the individual FRR daemons.

Currently VyOS has `protocol igmp` option to enable IGMP querier and reports through FRR's pimd.
I would like to add support for IPv6 as well since FRR's IPv6 multicast functionality has significantly improved.
Enabling both MLD and IGMP on a VyOS router will allow us to turn on multicast snooping on layer-3 switches in dual-stack networks.
Example commands:
```
// Enable on interface eth0
set protocols pim6 interface eth0
// Explicitly join multicast group ff18::1234 on interface eth1
set protocols pim6 interface eth1 mld join ff18::1234
// Explicitly join source-specific multicast group ff38::5678 with source address 2001:db8::1 on interface eth1
set protocols pim6 interface eth1 mld join ff38::5678 source 2001:db8::1
```
