sync/atomic must be used with 64-bit aligned fields, and that alignment is difficult to
ensure unless the field is the first one in the struct.
https://golang.org/pkg/sync/atomic/#pkg-note-BUG.
As part of this change, we ensure that the SAN extensions are marked as
critical when the subject is empty so that AWS PCA tolerates the loss of
common names well and continues to function as a Connect CA provider.
Parts of this currently hack around a bug in crypto/x509 and can be
removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.
Note: the AWS PCA tests do not run automatically, but the following
passed locally for me:

* ui: Move all our icons to use CSS custom properties
The good thing about SASS vars is, if you don't use them they get removed from the final build. Whereas with CSS we have no tree-shaking to get rid of unused CSS custom properties. We can mostly work around this and for some things like colors its no big deal if we have some hex-codes in the build that we don't use as hex-codes are relatively small.
We've been slowly but surely moving all of our colors (and other things) to use CSS custom properties instead of SASS vars now that we have them available.
This commit makes use of the 'tree-shaking' abilities of @extend to ensure that we only compile in the icons that we use.
This commit is mostly churn-less as we already use @extend for the majority of our icons, so generally there is zero change here for working on the UI, but I did spot one single place where we were using SASS vars instead of @extend. This now uses the new form (second commit)
Interestingly this reduces our CSS payload by ~2kb to ~53kb (around 25kb of that is these icons)

* flush every 500ms to optimize log writing in the http server side.
* add changelog file

Updates to a cluster will clear the associated endpoints, and updates to
a listener will clear the associated routes. Update the incremental xDS
logic to account for this implicit cleanup so that we can finish warming
the clusters and listeners.
Fixes#10379
Previously we would return an error if duplicate paths were specified.
This could lead to problems in cases where a user has the same path,
say /healthz, on two different ports.
This validation was added to signal a potential misconfiguration.
Instead we will only check for duplicate listener ports, since that is
what would lead to ambiguity issues when generating xDS config.
In the future we could look into using a single listener and creating
distinct filter chains for each path/port.
* debug: remove the CLI check for debug_enabled
The API allows collecting profiles even debug_enabled=false as long as
ACLs are enabled. Remove this check from the CLI so that users do not
need to set debug_enabled=true for no reason.
Also:
- fix the API client to return errors on non-200 status codes for debug
endpoints
- improve the failure messages when pprof data can not be collected

This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
Normally the named pipe would buffer up to 64k, but in some cases when a
soft limit is reached, they will start only buffering up to 4k.
In either case, we should not deadlock.
This commit changes the pipe-bootstrap command to first buffer all of
stdin into the process, before trying to write it to the named pipe.
This allows the process memory to act as the buffer, instead of the
named pipe.
Also changed the order of operations in `makeBootstrapPipe`. The new
test added in this PR showed that simply buffering in the process memory
was not enough to fix the issue. We also need to ensure that the
`pipe-bootstrap` process is started before we try to write to its
stdin. Otherwise the write will still block.
Also set stdout/stderr on the subprocess, so that any errors are visible
to the user.

The bulk of this commit is moving the LeaderRoutineManager from the agent/consul package into its own package: lib/gort. It also got a renaming and its Start method now requires a context. Requiring that context required updating a whole bunch of other places in the code.
