It turns out that circuit_package_relay_cell() returns 0 in order to drop a
cell but there is a code path, if the circuit queue is full, that also silently
closes the circuit and returns 0.
This lead to Conflux thinking a cell was sent but actually the cell was not and
the circuit was closed leading to the hard assert.
And so this function makes sure that circuit_package_relay_cell() and
append_cell_to_circuit_queue() returns a value that indicate what happened with
the cell and circuit so the caller can make an informed decision with it.
This change makes it that we do NOT enter the Conflux subsystem if the cell is
not queued on the circuit.

This was previously added to facilitate testing intro point rotation
with chutney. However, the implementation is problematic since it forces
excessive rotation whenever TestingTorNetwork is enabled, and can't be
adjusted or disabled.
Alternatives for testing intro point rotation include:
* Using shadow to "fast forward" time
* Overriding the consensus parameters hs_intro_min_lifetime and
hs_intro_max_lifetime.
Fixes#40922
Allow "node_id" KeyValue without the dollar sign at the start of the
hexdigit in the BandwidthFiles, in order to easier database queries
combining Tor documents in which the relays fingerprint doesn't
include it.
Bugfix on all supported versions of Tor.
Closes#40891
This commit adds the total number of DROP cell seen, the total number of
DESTROY cell received and the total number of protocol violation that lead to a
circuit close.

The hs_metrics_failed_rdv() macro could pass a NULL value for the identity key
when a building circuit would end up in a failure path *before* the "hs_ident"
was able to be set which leading to this assert.
This was introduced in 0.4.8.1-alpha with the addition of rendezvous circuit
failure metrics for the MetricsPort.
This fixes TROVE-2023-006 for which its severity is considered high.
