* cmd/k8s-operator: users can configure operator to set firewall mode for proxies
Users can now pass PROXY_FIREWALL_MODE={nftables,auto,iptables} to operator to make it create ingress/egress proxies with that firewall mode
Also makes sure that if an invalid firewall mode gets configured, the operator will not start provisioning proxy resources, but will instead log an error and write an error event to the related Service.

Previously we were just smushing together args and not trying
to parse the values at all. This resulted in the args to testwrapper
being limited and confusing.
This makes it so that testwrapper parses flags in the exact format as `go test`
command and passes them down in the provided order. It uses tesing.Init to
register flags that `go test` understands, however those are not the only
flags understood by `go test` (such as `-exec`) so we register these separately.

This partially reverts commits a61a9ab087
and 7538f38671 and fully reverts
4823a7e591.
The goal of that commit was to reapply known config whenever the
container restarts. However, that already happens when TS_AUTH_ONCE was
false (the default back then). So we only had to selectively reapply the
config if TS_AUTH_ONCE is true, this does exactly that.
This is a little sad that we have to revert to `tailscale up`, but it
fixes the backwards incompatibility problem.

The old code would always retain value `true` if it was set once, even
if you then change `prefs.AutoUpdate.Apply` to `false`.
Instead of using the previous value, use the default (envknob) value to
OR with.

Signed-off-by: Joe Tsai <joetsai@digital-static.net>
We add the following API:
* type FileChecksums
* type Checksum
* func Manager.PartialFiles
* func Manager.HashPartialFile
* func ResumeReader
The Manager methods provide the ability to query for partial files
and retrieve a list of checksums for a given partial file.
The ResumeReader function is a helper that wraps an io.Reader
to discard content that is identical locally and remotely.
The FileChecksums type represents the checksums of a file
and is safe to JSON marshal and send over the wire.

We were eagerly doing a synchronous renewal of the cert while
trying to serve traffic. Instead of that, just do the cert
renewal in the background and continue serving traffic as long
as the cert is still valid.
This regressed in c1ecae13ab when
we introduced ARI support and were trying to make the experience
of `tailscale cert` better. However, that ended up regressing
the experience for tsnet as it would not always doing the renewal
synchronously.

In almost every single use of Clock, there is a default behavior
we want to use when the interface is nil,
which is to use the the standard time package.
The Clock interface exists only for testing,
and so tests that care about mocking time
can adequately plumb the the Clock down the stack
and through various data structures.
However, the problem with Clock is that there are many
situations where we really don't care about mocking time
(e.g., measuring execution time for a log message),
where making sure that Clock is non-nil is not worth the burden.
In fact, in a recent refactoring, the biggest pain point was
dealing with nil-interface panics when calling tstime.Clock methods
where mocking time wasn't even needed for the relevant tests.
This required wasted time carefully reviewing the code to
make sure that tstime.Clock was always populated,
and even then we're not statically guaranteed to avoid a nil panic.
Ideally, what we want are default methods on Go interfaces,
but such a language construct does not exist.
However, we can emulate that behavior by declaring
a concrete type that embeds the interface.
If the underlying interface value is nil,
it provides some default behavior (i.e., use StdClock).
This provides us a nice balance of two goals:
* We can plumb tstime.DefaultClock in all relevant places
for use with mocking time in the tests that care.
* For all other logic that don't care about,
we never need to worry about whether tstime.DefaultClock
is nil or not. This is especially relevant in production code
where we don't want to panic.
Longer-term, we may want to perform a large-scale change
where we rename Clock to ClockInterface
and rename DefaultClock to just Clock.

Changes made:
* Move all HTTP related functionality from taildrop to ipnlocal.
* Add two arguments to taildrop.Manager.PutFile to specify
an opaque client ID and a resume offset (both unused for now).
* Cleanup the logic of taildrop.Manager.PutFile
to be easier to follow.
* Implement file conflict handling where duplicate files are renamed
(e.g., "IMG_1234.jpg" -> "IMG_1234 (2).jpg").
* Implement file de-duplication where "renaming" a partial file
simply deletes it if it already exists with the same contents.
* Detect conflicting active puts where a second concurrent put
results in an error.
