Paul Banks 5b0d4db6bc Support Agent Caching for Service Discovery Results (#4541)
* Add cache types for catalog/services and health/services and basic test that caching works

* Support non-blocking cache types with Cache-Control semantics.

* Update API docs to include caching info for every endpoint.

* Comment updates per PR feedback.

* Add note on caching to the 10,000 foot view on the architecture page to make the new data path more clear.

* Document prepared query staleness quirk and force all background requests to AllowStale so we can spread service discovery load across servers.

# Certificate Authority (CA) - Connect HTTP API
The `/connect/ca` endpoints provide tools for interacting with Connect's
Certificate Authority mechanism.
## List CA Root Certificates
This endpoint returns the current list of trusted CA root certificates in
the cluster.

## Update CA Configuration
This endpoint updates the configuration for the CA. If this results in a
new root certificate being used, the [Root Rotation]

### Parameters
- `Provider` `(string: <required>)` - Specifies the CA provider type to use.
- `Config` `(map[string]string: <required>)` - The raw configuration to use
for the chosen provider. For more information on configuring the Connect CA
providers, see [Provider Config](/docs/connect/ca.html).
### Sample Payload
```json
{
"Provider": "consul",
"Config": {
