frr-reload triggers restart of service in case
it fails to parse new config file and conjunction with
running config contains 'router bgp' (default bgp instnace).
When frr-reload fails to parse new config file, it fails
to build newconfig context (empty object).
Instead of bailing out it compares against the running config
context. If the running config contains default bgp instance
it thinks new config is removing default bgp instance so it
triggers frr restart.
Fix is to to bail out reload script when it fails to parse
config file.

This utility script helps in generated formatted and consistent
change log including:
1- group logs per daemon
2- standarize daemon names (lowercase, end with d)
3- capitalize all log lines
4- no merge commits
caveat: comments are assumed to be in the form
daemon-name : message
Sample Output:

Remove neighbor <> remote-as <> config line,
if the neighbor is part of the peer-group and
peer-group contains remote-as config.
Neighbors which are part of the peer-group
cannot override remote-as.
Fix:
Frr-reload needs to remote 'neighbor <> remote-as <>'
from lines_to_add if its already part of peer-group
and peer-group has remote-as config.
Testing Done:
Before:
Config snippet:
neighbor PEERS peer-group
neighbor PEERS remote-as external
neighbor PEERS timers 3 9
neighbor 10.2.1.1 remote-as external
neighbor 10.2.1.1 peer-group PEERS
neighbor 10.2.1.1 timers 3 9
neighbor 10.2.1.2 remote-as external
neighbor 10.2.1.2 peer-group PEERS
Frr-reload failure:
line 179: Failure to communicate[13] to bgpd, line: neighbor 10.2.1.1
remote-as external
% Peer-group member cannot override remote-as of peer-group
line 179: Failure to communicate[13] to bgpd, line: neighbor 10.2.1.2
remote-as external
% Peer-group member cannot override remote-as of peer-group
After:
frr-reload apply the config successfully.

These aren't appropriate for use in FRR. Among other things, this

This allows defining a CLI command like this:
`[no] some setting ![VALUE]`
with VALUE being optional for the "no" form, but required for the
positive form. It's just a `[...]` where the empty branch can only be
taken for commands starting with `no`.

Currently, in frr-reload we:
- store a list of single-line context keywords which needs to be
frequently updated,
- have a separate "if" clause for every node and subnode we have in FRR.
Instead, we can store the tree of all known FRR nodes. This tree needs
to be updated whenever we add a new node, which is not frequent. And,
most importantly, it allows us to write node-agnostic code and save more
than 250 LOC.
