The previous commit 58ab66e added ssh/tailssh/user.go as part of
working on #4945. So move some more user-related code over to it.

Current code will set the "dirty" field of VersionInfo always "true"
if vcs.modified flag is there. No matter whether the flag is "true" or
"false". It will make sense to set this field due to vcs.modified
value, not only the existence of the key.

in commit 6e96744, the tsd system type has been added.
Which will cause the daemon will crash on some OSs (Windows, darwin and so on).
The root cause is that on those OSs, handleSubnetsInNetstack() will return true and set the conf.Router with a wrapper.
Later in NewUserspaceEngine() it will do subsystem set and found that early set router mismatch to current value, then panic.
expvar can only be defined once, so running tests with a repeat counter
will fail if the variables are defined inside of the test function.
Observed failure:

`interfaces.Tailscale()` returns all zero values when it finds no
Tailscale interface and encounters no errors. The netns package was
treating no error as a signal that it would receive a non-zero pointer

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

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.

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.
