Examples covering a variety of potential use cases. Verified via `sockaddr eval` and `console agent -bind` on a test machine:
```console
# Baseline
$ sockaddr eval 'GetAllInterfaces'
[127.0.0.1/8 {1 65536 lo up|loopback} ::1 {1 65536 lo up|loopback} 10.0.0.10/8 {2 1500 eth0 b8:27:eb:7b:36:95 up|broadcast|multicast} fe80::12dc:5e4d:8ff8:2d96/64 {2 1500 eth0 b8:27:eb:7b:36:95 up|broadcast|multicast} 192.168.1.10/24 {3 1500 wlan0 b8:27:eb:2e:63:c0 up|broadcast|multicast} fe80::b6dc:5758:c306:b15b/64 {3 1500 wlan0 b8:27:eb:2e:63:c0 up|broadcast|multicast}]
# Using address within a specific CIDR
$ sockaddr eval 'GetPrivateInterfaces | include "network" "10.0.0.0/8" | attr "address"'
10.0.0.10
# Using a static network interface name
$ sockaddr eval 'GetInterfaceIP "eth0"'
10.0.0.10
# Using regular expression matching for network interface name that is forwardable and up
$ sockaddr eval 'GetAllInterfaces | include "name" "^eth" | include "flags" "forwardable|up" | attr "address"'
10.0.0.10
```

When set to notify, systemd will not attempt to start any dependent
services until after consul sends the notify signal. This is useful
in cases where there services that rely on the local consul agent
to be up and functional before they can start. The default is simple,
which will immediately mark the service as up and functioning even
if consul has not yet joined the cluster and has started listening
for connnections.

# Data Filtering
This PR will implement filtering for the following endpoints:
## Supported HTTP Endpoints
- `/agent/checks`
- `/agent/services`
- `/catalog/nodes`
- `/catalog/service/:service`
- `/catalog/connect/:service`
- `/catalog/node/:node`
- `/health/node/:node`
- `/health/checks/:service`
- `/health/service/:service`
- `/health/connect/:service`
- `/health/state/:state`
- `/internal/ui/nodes`
- `/internal/ui/services`
More can be added going forward and any endpoint which is used to list some data is a good candidate.
## Usage
When using the HTTP API a `filter` query parameter can be used to pass a filter expression to Consul. Filter Expressions take the general form of:
```
<selector> == <value>
<selector> != <value>
<value> in <selector>
<value> not in <selector>
<selector> contains <value>
<selector> not contains <value>
<selector> is empty
<selector> is not empty
not <other expression>
<expression 1> and <expression 2>
<expression 1> or <expression 2>
```
Normal boolean logic and precedence is supported. All of the actual filtering and evaluation logic is coming from the [go-bexpr](https://github.com/hashicorp/go-bexpr) library
## Other changes
Adding the `Internal.ServiceDump` RPC endpoint. This will allow the UI to filter services better.
* [docs] security warning about Helm chart
Correct security warning about helm chart to caution about default Consul install.
* clarify that k8s or consul should be secure
* website: specify value of acquire/release params for kv
* website: clarify leader election usage in TTL docs
* website: document minimal value of lockdelay
I believe it uses the default when parsing 0 as it
views that as an empty parameter in this case.
