At this commit, a new service registers to the module and a store is created.
It also remove itself from the metrics module if it goes away.

In order to hook into the metrics subsystem, this commit attaches the HS
subsystem into the subsystem global list so its get_metrics() call can be
accessible.

HS initialization is still _not_ done through the subsys module as it is
likely require much more testing.

First I began with a set of candidates:

  The client's _required_ list starts with all the protocols
  supported by every release in 0.2.9-stable through current
  master.

  The client's _required_ list starts with all the protocols
  supported by every release in 0.3.5-stable through current
  master.

  Everybody's _recommended_ list starts with all the protocols
  supported by every release in 0.3.5-stable through current master.

Then I removed the protocol versions that we do not actually want to
require or recommend:

  DirCache=1 (deprecated)
  HSDir=1, HSIntro=1-3, HSRend=1 (deprecated)
  (All HS* protocol requirements for clients)
  Link=1-3 (deprecated)
  LinkAuth=1 (obsolete)
  Relay=1 (obsolete)

Make it possible to specify multiple ConsensusParams torrc
lines.

Now directory authority operators can for example put the
main ConsensusParams config in one torrc file and then add to it
from a different torrc file.

Affected entries are: EntryNodes, ExcludeNodes, ExcludeExitNodes,
ExitNodes, MiddleNodes, HSLayer2Nodes and HSLayer3Nodes.

When calling `circpad_send_padding_cell_for_callback()`, the flag
`is_padding_timer_scheduled` was not resetted to 0 which caused an issue
in the circpad simulator.
This commit fixes this problem.

Fixes #32671.

Tor does not follow redirects when bootstraping so we encountered an
error.

Fixes #40053

Also, explain why it's relevant for bootstrapping.

This is a comments-only patch.

  Cons=1 is the old format of consensuses, without ed25519 keys. It
  is no longer required or recommended.

  Cons=2 is the new format of consensuses, with ed25519 keys. It
  is now required.

  (Similarly for Desc=1,2 and Microdesc=1,2)

No supported client or relay versions should be affected by this
change, since these versions are supported by clients and relays
running 0.2.9 and later.  It will only take effect once enough
authorities vote for it.

Closes ticket 40162.

This should make diffs easier to read.
