ACL Authorizer overhaul (#6620)
* ACL Authorizer overhaul

To account for upcoming features every Authorization function can now take an extra *acl.EnterpriseAuthorizerContext. These are unused in OSS and will always be nil.

Additionally the acl package has received some thorough refactoring to enable all of the extra Consul Enterprise specific authorizations including moving sentinel enforcement into the stubbed structs. The Authorizer funcs now return an acl.EnforcementDecision instead of a boolean. This improves the overall interface as it makes multiple Authorizers easily chainable as they now indicate whether they had an authoritative decision or should use some other defaults. A ChainedAuthorizer was added to handle this Authorizer enforcement chain and will never itself return a non-authoritative decision.

* Include stub for extra enterprise rules in the global management policy

* Allow for an upgrade of the global-management policy

Expose HTTP-based paths through Connect proxy (#6446)
Fixes: #5396

This PR adds a proxy configuration stanza called expose. These flags register
listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only
listening on the loopback interface, while still accepting traffic from non
Connect-enabled services.

Under expose there is a boolean checks flag that would automatically expose all
registered HTTP and gRPC check paths.

This stanza also accepts a paths list to expose individual paths. The primary
use case for this functionality would be to expose paths for third parties like
Prometheus or the kubelet.

Listeners for requests to exposed paths are be configured dynamically at run
time. Any time a proxy, or check can be registered, a listener can also be
created.

In this initial implementation requests to these paths are not
authenticated/encrypted.

connect: introduce ExternalSNI field on service-defaults (#6324)
Compiling this will set an optional SNI field on each DiscoveryTarget.
When set this value should be used for TLS connections to the instances
of the target. If not set the default should be used.

Setting ExternalSNI will disable mesh gateway use for that target. It also 
disables several service-resolver features that do not make sense for an 
external service.

connect: updating a service-defaults config entry should leave an unset protocol alone (#6342)
If the entry is updated for reasons other than protocol it is surprising
that the value is explicitly persisted as 'tcp' rather than leaving it
empty and letting it fall back dynamically on the proxy-defaults value.

connect: expose an API endpoint to compile the discovery chain (#6248)
In addition to exposing compilation over the API cleaned up the structures that would be exchanged to be cleaner and easier to support and understand.

Also removed ability to configure the envoy OverprovisioningFactor.

handle structs.ConfigEntry decoding similarly to api.ConfigEntry decoding (#6106)
Both 'consul config write' and server bootstrap config entries take a
decoding detour through mapstructure on the way from HCL to an actual
struct. They both may take in snake_case or CamelCase (for consistency)
so need very similar handling.

Unfortunately since they are operating on mirror universes of structs
(api.* vs structs.*) the code cannot be identitical, so try to share the
kind-configuration and duplicate the rest for now.

Paul Banks 078f4cf5bb Add integration test for central config; fix central config WIP (#5752)
* Add integration test for central config; fix central config WIP

* Add integration test for central config; fix central config WIP

* Set proxy protocol correctly and begin adding upstream support

* Add upstreams to service config cache key and start new notify watcher if they change.

This doesn't update the tests to pass though.

* Fix some merging logic get things working manually with a hack (TODO fix properly)

* Simplification to not allow enabling sidecars centrally - it makes no sense without upstreams anyway

* Test compile again and obvious ones pass. Lots of failures locally not debugged yet but may be flakes. Pushing up to see what CI does

* Fix up service manageer and API test failures

* Remove the enable command since it no longer makes much sense without being able to turn on sidecar proxies centrally

* Remove version.go hack - will make integration test fail until release

* Remove unused code from commands and upstream merge

* Re-bump version to 1.5.0
