This passes the *dnscache.Resolver down from the Direct client into the
Noise client and from there into the controlhttp client. This retains
the Resolver so that it can share state across calls instead of creating
a new resolver.

Every time we change `installer.sh`, run it in a few docker
containers based on different Linux distros, just as a simple test.
Also includes a few changes to the installer script itself to make
installation work in docker:
- install dnf config-manager command before running it
- run zypper in non-interactive mode
- update pacman indexes before installing packages

The action cache restore process either matches the restore key pattern
exactly, or uses a matching prefix with the most recent date.
If the restore key is an exact match, then no updates are uploaded, but
if we've just computed tests executions for more recent code then we
will likely want to use those results in future runs.
Appending run_id to the cache key will give us an always new key, and
then we will be restore a recently uploaded cache that is more likely
has a higher overlap with the code being tested.

DERP doesn't support HTTP/2. If an HTTP/2 proxy was placed in front of
a DERP server requests would fail because the connection would
be initialized with HTTP/2, which the DERP client doesn't support.

This fix does not seem ideal, but the test infrastructure using a local
goos doesn't seem to avoid all of the associated challenges, but is
somewhat deeply tied to the setup.
The core issue this addresses for now is that when run on Windows there
can be no code paths that attempt to use an invalid UID string, which on
Windows is described in [1].
For the goos="linux" tests, we now explicitly skip the affected
migration code if runtime.GOOS=="windows", and for the Windows test we
explicitly use the running users uid, rather than just the string
"user1". We also now make the case where a profile exists and has
already been migrated a non-error condition toward the outer API.

Looks like on some systems there's an IPv6 address, but then opening
a IPv6 UDP socket fails later. Probably some firewall. Tolerate it
better and don't crash.
To repro: check the "udp6" to something like "udp7" (something that'll
fail) and run "go run ./cmd/tailscale netcheck" on a machine with
active IPv6. It used to crash and now it doesn't.

On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available
(i.e. when a phone has no connectivity, we log an error and thus cause
more things that we will try to upload and fail).
Fixed by passing around a netmon.Monitor to more places, so that we can
use its cached interface state.

We're using it in more and more places, and it's not really specific to
our use of Wireguard (and does more just link/interface monitoring).
Also removes the separate interface we had for it in sockstats -- it's
a small enough package (we already pull in all of its dependencies
via other paths) that it's not worth the extra complexity.

Found this when adding a test that does a ping over PeerAPI.
Our integration tests set up a trafficTrap to ensure that tailscaled
does not call out to the internet, and it does so via a HTTP_PROXY.
When adding a test for pings over PeerAPI, it triggered the trap and investigation
lead to the realization that we were not removing the Proxy when trying to
dial out to the PeerAPI.

Exposes some internal state of the sockstats package via the C2N and
PeerAPI endpoints, so that it can be used for debugging. For now this
includes the estimated radio on percentage and a second-by-second view
of the times the radio was active.
Also fixes another off-by-one error in the radio on percentage that
was leading to >100% values (if n seconds have passed since we started
to monitor, there may be n + 1 possible seconds where the radio could
have been on).

When splitting the radio monitor usage array, we were splitting at now %
3600 to get values into chronological order. This caused the value for
the final second to be included at the beginning of the ordered slice
rather than the end. If there was activity during that final second, an
extra five seconds of high power usage would get recorded in some cases.
This could result in a final calculation of greater than 100% usage.
This corrects that by splitting values at (now+1 % 3600).
This also simplifies the percentage calculation by always rounding
values down, which is sufficient for our usage.

Exclude traffic with 100.100.100.100 (for IPv4) and
with fd7a:115c:a1e0::53 (for IPv6) since this traffic with the
Tailscale service running locally on the node.
This traffic never left the node.
It also happens to be a high volume amount of traffic since
DNS requests occur over UDP with each request coming from a
unique port, thus resulting in many discrete traffic flows.
