Now it only uses the telemetry messages directly rather than the metric system.
This is much faster and more direct, and removes a blocker on improving the
metrics support.
Also fixes the fact that recieced and sent were the wrong way round before,
probably as an artifact of the old protocol logging code, and also removes
the bytes histogram which was a lie (it was a histogram of write sizes that
was presented as a histogram of message sizes)

When determining the root directory of a module, the go list overlay
code would do a go list -m all to get the module information for all
modules. Stop doing that and only list the current module. This fixes
an issue when users had overlays and were using automatic vendoring
because go list -m all doesn't work with automatic vendoring.
It isn't clear if overlays outside of the main module were ever working
and overlays in the module cache don't make sense. There's a chance that
this might break users with overlays in replaced directories, but it's
not clear that that previously worked, and it wasn't tested. If this
change causes breakages, we can use bcmills' suggestion in

One of the tricky things about asserting on conditions in regtests is
the asynchronous nature of LSP. For example, as the LSP client we cannot
be sure when we've received all diagnostics for a given file.
Currently, regtests are implemented by awaiting specific diagnostic
expectations. This means that if gopls generates diagnostics that do
not match those expectations, we can only time out the test.
Ideally, we would want to know that gopls is done generating all diagnostics
for the current file state. This is not possible without knowing the
status of diagnostics for. Barring this, we would want to know that
diagnostics are done for the current file version. Unfortunately, that
also is not possible, because a new version of file B can affect
diagnostics in file A.
So in lieu of this information, this CL exposes a few tools that can be
used to improve the experience of writing new regtests.
- A new expectation is added: AnyDiagnosticAtCurrentVersion, that is
satisfied if any diagnostics have been received for the current
buffer version.
- ExpectDiagnostics is added to Env, to help check whether the current
diagnostics matches expectations.

fully typed, and they're probably pretty relevant. I hadn't bothered
doing that for package names, because the first two reasons aren't very
relevant. But the third still is -- loaded packages are a pretty good
approximation for in module scope, etc.
With this change we do package names the same as members, so relevance
should be about as good. Not perfect, but nobody's complained much yet.
Fair bit of copy-and-paste, but I don't want to extend the
