Once the cpath is finalized, e2e encryption setup, transfer the ccontrol
from the rendezvous circuit to the cpath.
This allows the congestion control subsystem to properly function for
both upload and download side of onion services.

Introduces two new consensus parameter:
exit_dns_timeout: Number of seconds before libevent should consider

previously failing query before calling it a timeout.

Due to a possible Guard subsystem recursion, when the HS client gets
notified that the directory information has changed, it must run it in a
seperate mainloop event to avoid such issue.
See the ticket for more information on the recursion. This also fixes a
fatal assert.

It is possible to not have the descriptor anymore by the time the
rendezvous circuit opens. Don't BUG() on that.
Instead, when sending the INTRODUCE1 cell, make sure the descriptor we
have (or have just fetched) matches what we setup in the rendezvous
circuit.
If not, the circuit is closed and another one is opened for a retry.

Prometheus needs unique labels and so this bug was causing an onion
service with multiple ports to have multiple "port=" label for the
metrics requiring a port label.

It is possible that a scheduled channel ended up with 0 bytes in its
outbuf after the scheduling loop and having an outbuf table entry
indicating that we need to flush bytes on the wire after the loop.
This lead to attempt to write 0 bytes up to the TLS layer that would
prevent such action.
All in all, this fixes wasted CPU cycles on attempting to flush nothing.

We removed HSIntro=3 and HSDir=1 that are v2 specific. Since 0.3.5.17,
we do not support introducing or being a directory for onion service v2.
