Changes the DNS cache to respect the advertised TTL, modulo a floor of 5s.
That part of the change is runtime guard. The part which is not, is that the backoff is done on a per-host basis not a global basis, so if one endpoint fails to resolve, it won't result in others backing off, and if one succeeds it won't result in changing backoff for failed hosts.
Risk Level: Medium

Adding a core.v3.TypedExtensionConfig typed_dns_resolver_config for DNS resolver
in API definition. This configuration is to support DNS resolution as a first
class Envoy extension. This API change is the first step for that task.
This configuration is to replace above dns_resolution_config.
By default envoy supports c-ares DNS or apple DNS resolvers. This extension can be used
to configure other DNS resolver types.
This configuration is optional. In case it is missing, the default behavior is in place,
which means Envoy will either use c-ares DNS library or apple DNS library based on
the compiling flag. When this configuration is in place, Envoy will use the configured
DNS resolver carried in the extension typed_config field.
In case both typed_dns_resolver_config and dns_resolution_config are configured,
typed_dns_resolver_config take precedence.

Commit Message: this PR adds the ability to prefetch hostnames to resolve during cache construction.
Additional Description: This feature can be used as a performance improvement for setups that use dns cache, but know a priori some of the hostnames that will be used.
Risk Level: low -- adds a feature that is off by default.
Testing: new tests
Docs Changes: added documentation in the API

We will want the same DNS configuration options from the Cluster in
the Dynamic Forward Proxy’s DNS configuration.

In the current implementation of the DNS cache, circuit breaker is derived from cluster config. It seems unnatural. In this PR, I implemented the DNS cache specific circuit breaker by adding resource manager to that.

This patch performs a major version freeze and bump by modifying
package_version_status, using the tooling developed in #10636.
Specifically:
v2 APIs are frozen (except for where they are the latest in their
package history and still active)
v3 APIs are transitioned to be active
Candidate v4alpha APIs are generated (not used by Envoy yet)
Fixes#10355
Risk level: medium (entire API's files are modified, visually verified
to ensure things look sane, all tests pass)
Testing: CI

Part of https://github.com/envoyproxy/envoy/issues/10355, this patch introduces additional
annotations to the API to support automatic inference (and developer documentation) of where the
active developer editable version of a file is, and which files are frozen or machine generated.
Risk level: Low (API annotations only)
Testing: CI

In which we convert every v3alpha reference to v3. In future revs of the
stable API versioning policy, we will develop better tooling to support
> 2 alpha and stable versions. For v3, it seems reasonable to just mv
v3alpha to v3, since there should be no external consumers yet.
Risk level: Low
