Remove some usage of md5 from the system (#11491)
* Remove some usage of md5 from the system

OSS side of https://github.com/hashicorp/consul-enterprise/pull/1253

This is a potential security issue because an attacker could conceivably manipulate inputs to cause persistence files to collide, effectively deleting the persistence file for one of the colliding elements.

Daniel Nephin b8da06a34d acl: remove ACL upgrading from Clients
As part of removing the legacy ACL system ACL upgrading and the flag for
legacy ACLs is removed from Clients.

This commit also removes the 'acls' serf tag from client nodes. The tag is only ever read
from server nodes.

This commit also introduces a constant for the acl serf tag, to make it easier to track where
it is used.

Daniel Nephin bd28d23b55 command/envoy: stop using the DebugConfig from Self endpoint
The DebugConfig in the self endpoint can change at any time. It's not a stable API.

This commit adds the XDSPort to a stable part of the XDS api, and changes the envoy command to read
this new field.

It includes support for the old API as well, in case a newer CLI is used with an older API, and
adds a test for both cases.

Add failures_before_warning to checks (#10969)
Signed-off-by: Jakub Sokołowski <jakub@status.im>

* agent: add failures_before_warning setting

The new setting allows users to specify the number of check failures
that have to happen before a service status us updated to be `warning`.
This allows for more visibility for detected issues without creating
alerts and pinging administrators. Unlike the previous behavior, which
caused the service status to not update until it reached the configured
`failures_before_critical` setting, now Consul updates the Web UI view
with the `warning` state and the output of the service check when
`failures_before_warning` is breached.

The default value of `FailuresBeforeWarning` is the same as the value of
`FailuresBeforeCritical`, which allows for retaining the previous default
behavior of not triggering a warning.

When `FailuresBeforeWarning` is set to a value higher than that of
`FailuresBeforeCritical it has no effect as `FailuresBeforeCritical`
takes precedence.

Daniel Nephin 047abdd73c acl: remove ACLDatacenter
This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.

This change was made by GoLand refactor, which did most of the work for me.

Daniel Nephin 1e23d181b5 config: remove misleading UseTLS field
This field was documented as enabling TLS for outgoing RPC, but that was not the case.
All this field did was set the use_tls serf tag.

Instead of setting this field in a place far from where it is used, move the logic to where
the serf tag is set, so that the code is much more obvious.

Daniel Nephin 3c60a46376 config: remove duplicate TLSConfig fields from agent/consul.Config
tlsutil.Config already presents an excellent structure for this
configuration. Copying the runtime config fields to agent/consul.Config
makes code harder to trace, and provides no advantage.

Instead of copying the fields around, use the tlsutil.Config struct
directly instead.

This is one small step in removing the many layers of duplicate
configuration.

Support Incremental xDS mode (#9855)
This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged.

Union of all commit messages follows to give an overarching summary:

xds: exclusively support incremental xDS when using xDS v3

Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail.
Work around a strange older envoy behavior involving empty CDS responses over incremental xDS.
xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support

Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead.
Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client.
xds: pull out checkStreamACLs method in advance of a later commit

xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings

In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty.

This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10.

xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

Daniel Nephin 18c9e73832 connect: do not set QuerySource.Node
Setting this field to a value is equivalent to using the 'near' query paramter.
The intent is to sort the results by proximity to the node requesting
them. However with connect we send the results to envoy, which doesn't
care about the order, so setting this field is increasing the work
performed for no gain.

It is necessary to unset this field now because we would like connect
to use streaming, but streaming does not support sorting by proximity.

api: ensure v1/health/ingress/:service endpoint works properly when streaming is enabled (#9967)
The streaming cache type for service health has no way to handle v1/health/ingress/:service queries as there is no equivalent topic that would return the appropriate data.

Ensure that attempts to use this endpoint will use the old cache-type for now so that they return appropriate data when streaming is enabled.

Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes #9473.
