As helper function of Segment Routing Flex Algo or RSVP-TE
add Constrained Shortest Path First algorithm able to compute
path with constraints. Supported constraints are as follow:
- Standard IGP metric
- TE IGP metric
- Delay metric
- Bandwidth for given Class of Service for bandwidth reservation (RSVP-TE)
Usage of CSPF algorithms is detailed in the doc/developer/cspf.rst file

Opaque data takes up a lot of memory when there are a lot of routes on
the box. Given that this is just a cosmetic info, I propose to disable
it by default to not shock people who start using FRR for the first time
or upgrades from an old version.

Here "new" is very puzzling. If new parameters with default values on peer
configuration node are set, they will not be used yet.
So just clarify it:
Only "non-default" values on peer configuration node are set, they can override
the conrresponding values from profile.

rfc7196 recommends:
In addition, BGP implementations have an internal constant, which we
will call the 'maximum penalty', and the current computed penalty may
not exceed it.
Router Maximum Penalty: The internal constant for the maximum

Currently, it is possible to rename the default VRF either by passing
`-o` option to zebra or by creating a file in `/var/run/netns` and
binding it to `/proc/self/ns/net`.
In both cases, only zebra knows about the rename and other daemons learn
about it only after they connect to zebra. This is a problem, because
daemons may read their config before they connect to zebra. To handle
this rename after the config is read, we have some special code in every
single daemon, which is not very bad but not desirable in my opinion.
But things are getting worse when we need to handle this in northbound
layer as we have to manually rewrite the config nodes. This approach is
already hacky, but still works as every daemon handles its own NB
structures. But it is completely incompatible with the central
management daemon architecture we are aiming for, as mgmtd doesn't even
have a connection with zebra to learn from it. And it shouldn't have it,
because operational state changes should never affect configuration.
To solve the problem and simplify the code, I propose to expand the `-o`
option to all daemons. By using the startup option, we let daemons know
about the rename before they read their configs so we don't need any
special code to deal with it. There's an easy way to pass the option to
all daemons by using `frr_global_options` variable.
Unfortunately, the second way of renaming by creating a file in
`/var/run/netns` is incompatible with the new mgmtd architecture.
Theoretically, we could force daemons to read their configs only after
they connect to zebra, but it means adding even more code to handle a
very specific use-case. And anyway this won't work for mgmtd as it
doesn't have a connection with zebra. So I had to remove this option.
