This way we avoid serializing these when empty. Otherwise users of the
latest version of the api submodule cannot interact with older versions
of Consul, because a new api client would send keys that the older Consul
doesn't recognize yet.
The zero value of these flags was already being excluded in the xDS
generation of circuit breaker/outlier detection config.
See: makeThresholdsIfNeeded and ToOutlierDetection.
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.

* Fix bug in cache where TTLs are effectively ignored
This mostly affects streaming since streaming will immediately return from Fetch calls when the state is Closed on eviction which causes the race condition every time.
However this also affects all other cache types if the fetch call happens to return between the eviction and then next time around the Get loop by any client.
There is a separate bug that allows cache items to be evicted even when there are active clients which is the trigger here.
* Add changelog entry
* Update .changelog/9978.txt
I changed this in https://github.com/hashicorp/consul/pull/8802#pullrequestreview-500779357 because
exceeding the MaxWait seemed wrong, but as other have pointed out, that behaviour is probably correct.
When multiple waiters hit the max value, we don't want them to converge, so restore the behaviour of
allowing jitter to exceed max, and document it.

Synthetic upstreams from service-defaults config are stored locally in
the Upstreams list. Since these come from service-defaults they should
be cleaned up locally when no longer present in the service config
response.
This is needed in case the client proxy is in TransparentProxy mode.
Typically they won't have explicit configuration for every upstream, so
this ensures the settings can be applied to all of them when generating
xDS config.
