frr: T6746: additional improvements after 10.2 upgrade (#4259)

* 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.
