Installer script relies on pkgs.tailscale.com being reachable, both for
checking what Linux distros are supported, but also for actually
downloading repo configuration files, gpg keys and packages themselves.
This change adds a simple reachability check which will print an error
message when pkgs.tailscale.com is not reachable.

This change introduces address selection for wireguard only endpoints.
If a endpoint has not been used before, an address is randomly selected
to be used based on information we know about, such as if they are able
to use IPv4 or IPv6. When an address is initially selected, we also
initiate a new ICMP ping to the endpoints addresses to determine which
endpoint offers the best latency. This information is then used to
update which endpoint we should be using based on the best possible
route. If the latency is the same for a IPv4 and an IPv6 address, IPv6
will be used.

In the case where the exit node requires SNAT, we would SNAT all traffic not just the
traffic meant to go through the exit node. This was a result of the default route being
added to the routing table which would match basically everything.
In this case, we need to account for all peers in the routing table not just the ones
that require NAT.
Fix and add a test.

Avoid selecting an endpoint as "better" than the current endpoint if the
total latency improvement is less than 1%. This adds some hysteresis to
avoid flapping between endpoints for a minimal improvement in latency.

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.

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.
