Add support for cookie authentication with bitcoind instead of
user/password. This is recommended when running eclair and
bitcoind on the same machine: it ensures only processes with
read permissions to the bitcoind cookie file are able to call the
RPC, which is safer than a user/password pair.
Having basic documentation in-place by providing examples in
`eclair.conf` is great and very convenient, but in the case of
path-finding, defining experiments take so much space that it makes
the whole configuration file actually more complicated to understand.
And since we don't want to enable experiments by default, the user still
has to figure out what to change to actually enable AB-testing.

We keep the GetRoutingState API available in the router as it's useful to
query network information locally (or between actors), but we stop sending
that data to remote nodes.
When we have a trusted relationship with some of our peers (business
relations, family members, our own mobile wallet, etc) it makes sense to
relax the feerate mismatch constraint.
This must be done per-node, to avoid leaving the gates open for attackers.
