Adds two new configuration parameters "dns_config.use_cache" and
"dns_config.cache_max_age" controlling how DNS requests use the agent
cache when querying servers.
* Add common blocking implementation details to docs
These come up over and over again with blocking query loops in our own code and third-party's. #5333 is possibly a case (unconfirmed) where "badly behaved" blocking clients cause issues, however since we've never explicitly documented these things it's not reasonable for third-party clients to have guessed that they are needed!
This hopefully gives us something to point to for the future.
It's a little wordy - happy to consider breaking some of the blocking stuff out of this page if we think it's appropriate but just wanted to quickly plaster over this gap in our docs for now.

The guide currently uses node, service, and service for the UI Policy.
This will cause a practically useless UI. This patch uses the _prefix
variants instead which will have the intended behavior.
It appears that the `read` command for ACL policies was used to template the `read` command for ACL tokens, and an invalid option was not dropped from the docs.
Given a query like:
```
{
"Name": "tagged-connect-query",
"Service": {
"Service": "foo",
"Tags": ["tag"],
"Connect": true
}
}
```
And a Consul configuration like:
```
{
"services": [
"name": "foo",
"port": 8080,
"connect": { "sidecar_service": {} },
"tags": ["tag"]
]
}
```
If you executed the query it would always turn up with 0 results. This was because the sidecar service was being created without any tags. You could instead make your config look like:
```
{
"services": [
"name": "foo",
"port": 8080,
"connect": { "sidecar_service": {
"tags": ["tag"]
} },
"tags": ["tag"]
]
}
```
However that is a bit redundant for most cases. This PR ensures that the tags and service meta of the parent service get copied to the sidecar service. If there are any tags or service meta set in the sidecar service definition then this copying does not take place. After the changes, the query will now return the expected results.
A second change was made to prepared queries in this PR which is to allow filtering on ServiceMeta just like we allow for filtering on NodeMeta.
* Support rate limiting and concurrency limiting CSR requests on servers; handle CA rotations gracefully with jitter and backoff-on-rate-limit in client
* Add CSR rate limiting docs
* Fix config naming and add tests for new CA configs
* Stared updaing links for the learn migration
* Language change cluster -> datacenter (#5212)
* Updating the language from cluster to datacenter in the backup guide to be consistent and more accurate.
* missed some clusters
* updated three broken links for the sidebar nav
Adds info about `k8stag` and `nodePortSyncType` options that were
added in consul-helm v0.5.0.
Additionally moves the k8sprefix to match the order in the Helm chart
values file, while also clarifying that it only affects one sync
direction.
If a user installs the default Helm chart Consul on a Kubernetes
cluster that is open to the internet, it is lacking some important
security configurations.

This endpoint aggregates all checks related to <service id> on the agent
and return an appropriate http code + the string describing the worst
check.
This allows to cleanly expose service status to other component, hiding
complexity of multiple checks.
This is especially useful to use consul to feed a load balancer which
would delegate health checking to consul agent.
Exposing this endpoint on the agent is necessary to avoid a hit on
consul servers and avoid decreasing resiliency (this endpoint will work
even if there is no consul leader in the cluster).

situations, hopefully clarifying things for users.
