Prevent partial application of Envoy extensions
Ensure that non-required extensions do not change xDS resources before
exiting on failure by cloning proto messages prior to applying each
extension.
To support this change, also move `CanApply` checks up a layer and make
them prior to attempting extension application, s.t. we avoid
unnecessary copies where extensions can't be applied.
Last, ensure that we do not allow panics from `CanApply` or `Extend`
checks to escape the attempted extension application.
When UpstreamEnvoyExtender was introduced, some code was left duplicated
between it and BasicEnvoyExtender. One path in that code panics when a
TProxy listener patch is attempted due to no upstream data in
RuntimeConfig matching the local service (which would only happen in
rare cases).
Instead, we can remove the special handling of upstream VIPs from
BasicEnvoyExtender entirely, greatly simplifying the listener filter
patch code and avoiding the panic. UpstreamEnvoyExtender, which needs
this code to function, is modified to ensure a panic does not occur.
This also fixes a second regression in which the Lua extension was not
applied to TProxy outbound listeners.
* add upstream service targeting to property override extension
* Also add baseline goldens for service specific property override extension.
* Refactor the extension framework to put more logic into the templates.
* fix up the golden tests
* Support Listener in Property Override
Add support for patching `Listener` resources via the builtin
`property-override` extension.
Refactor existing listener patch code in `BasicEnvoyExtender` to
simplify addition of resource support.
* Support ClusterLoadAssignment in Property Override
Add support for patching `ClusterLoadAssignment` resources via the
builtin `property-override` extension.
`property-override` is an extension that allows for arbitrarily
patching Envoy resources based on resource matching filters. Patch
operations resemble a subset of the JSON Patch spec with minor
differences to facilitate patching pre-defined (protobuf) schemas.
See Envoy Extension product documentation for more details.

To avoid unintended tampering with remote downstreams via service
config, refactor BasicEnvoyExtender and RuntimeConfig to disallow
typical Envoy extensions from being applied to non-local proxies.
Continue to allow this behavior for AWS Lambda and the read-only
Validate builtin extensions.
Addresses CVE-2023-2816.
Ensure nothing in the troubleshoot go module depends on consul's top level module. This is so we can import troubleshoot into consul-k8s and not import all of consul.
* turns troubleshoot into a go module [authored by @curtbushko]
* gets the envoy protos into the troubleshoot module [authored by @curtbushko]
* adds a new go module `envoyextensions` which has xdscommon and extensioncommon folders that both the xds package and the troubleshoot package can import
* adds testing and linting for the new go modules
* moves the unit tests in `troubleshoot/validateupstream` that depend on proxycfg/xds into the xds package, with a comment describing why those tests cannot be in the troubleshoot package
* fixes all the imports everywhere as a result of these changes
