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 09ae0ab94a acl: make ACLDisabledTTL a constant
This field was never user-configurable. We always overwrote the value with 120s from
NonUserSource. However, we also never copied the value from RuntimeConfig to consul.Config,
So the value in NonUserSource was always ignored, and we used the default value of 30s
set by consul.DefaultConfig.

All of this code is an unnecessary distraction because a user can not actually configure
this value.

This commit removes the fields and uses a constant value instad. Someone attempting to set
acl.disabled_ttl in their config will now get an error about an unknown field, but previously
the value was completely ignored, so the new behaviour seems more correct.

We have to keep this field in the AutoConfig response for backwards compatibility, but the value
will be ignored by the client, so it doesn't really matter what value we set.

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 843e08bb23 testing: fix a test for 32-bit
The hcl decoding apparently uses strconv.ParseInt, which fails to parse a 64bit int.
Since hcl v1 is basically EOl, it seems unlikely we'll fix this in hcl.

Since this test is only about loading values from config files, the extra large number
doesn't seem important. Trim a few zeros from the numbers so that they parse
properly on 32bit platforms.

Also skip a slow test when -short is used.

Rename CatalogDestinationsOnly (#10397)
CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.

This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.

Daniel Nephin bf4c289804 config-entry: remove Kind and Name field from Mesh config entry
No config entry needs a Kind field. It is only used to determine the Go type to
target. As we introduce new config entries (like this one) we can remove the kind field
and have the GetKind method return the single supported value.

In this case (similar to proxy-defaults) the Name field is also unnecessary. We always
use the same value. So we can omit the name field entirely.

Rename "cluster" config entry to "mesh" (#10127)
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.

Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.

freddygv eeccba945d Replace TransparentProxy bool with ProxyMode
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:

- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.

This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

Daniel Nephin e6badb3129 config: make TestLoad_IntegrationWithFlags easier to work with
Replace the large table of tests with individual calls to run(). By using
runCase, failure messages will include the line number for the test case, as
well as a line number from the test functions.

Example:
=== FAIL: agent/config TestLoad_IntegrationWithFlags/failing_case (0.01s)
    runtime_test.go:4721: case: failing case
    runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"

Previous:
    runtime_test.go:4864: error "data_dir cannot be empty" does not contain "I expected this error"

Without the line number to the testCase data, debugging these tests is
difficult. It is impossible to jump directly to the test case, and
difficult to find the location because of many similarly named cases.

This commit makes a number of changes that should make

real world scenarios.

* use separate files in testdata/ dir to store the config source.
  Separate files are much easier to edit because editors can syntax
  highlight json/hcl, and it makes strings easier to find. Previously
  trying to find strings would match strings used in other tests.
* use the exported config.Load interface instead of internal NewBuilder
  and BuildAndValidate.
* remove the tail config overrides, which are only necessary with
  nonZero works.

Daniel Nephin 8e783fb37b config: move testing shims to BuilderOpts
And remove the devMode field from builder.

This change helps make the Builder state more explicit by moving inputs to the BuilderOps struct,
leaving only fields that can change during Builder.Build on the Builder struct.

Daniel Nephin fcbdfa393e config: Use LiteralSource for some defaults
Using the LiteralSource makes it much easier to find default values, because an IDE reports
the location of a default. With an HCL string they are harder to discover.

Also removes unnecessary mapstructure.Decodes of constant values.

agent: return the default ACL policy to callers as a header (#9101)
Header is: X-Consul-Default-ACL-Policy=<allow|deny>

This is of particular utility when fetching matching intentions, as the
fallthrough for a request that doesn't match any intentions is to
enforce using the default acl policy.
