adding config for request_limits (#15531)
* server: add placeholder glue for rate limit handler

This commit adds a no-op implementation of the rate-limit handler and
adds it to the `consul.Server` struct and setup code.

This allows us to start working on the net/rpc and gRPC interceptors and
config logic.

* Add handler errors

* Set the global read and write limits

* fixing multilimiter moving packages

* Fix typo

* Simplify globalLimit usage

* add multilimiter and tests

* exporting LimitedEntity

* Apply suggestions from code review

* use timer to avoid go routine leak and change the interface

* add comments to tests

* fix failing test

* add prefix with config edge, refactor tests

* refactor to apply configs for limiters under a prefix

* add fuzz tests and fix bugs found. Refactor reconcile loop to have a simpler logic

* make KeyType an exported type

* split the config and limiter trees to fix race conditions in config update

* rename variables

* fix race in test and remove dead code

* fix reconcile loop to not create a timer on each loop

* removing the ignore of the request limits in JSON.  addingbuilder logic to convert any read rate or write rate less than 0 to rate.Inf

* added conversion function to convert request limits object to handler config.

* Updating docs to reflect gRPC and RPC are rate limit and as a result, HTTP requests are as well.

* Updating values for TestLoad_FullConfig() so that they were different and discernable.

* Updating TestRuntimeConfig_Sanitize

* Fixing TestLoad_IntegrationWithFlags test

* putting nil check in place

* fixing rebase

* removing change for missing error checks.  will put in another PR

* Rebasing after default multilimiter config change

* resolving rebase issues

server: add placeholder glue for rate limit handler (#15539)
Adds a no-op implementation of the rate-limit handler and exposes
it on the consul.Server struct.

It allows us to start working on the net/rpc and gRPC interceptors
and config (re)loading logic, without having to implement the full
handler up-front.
