RateLimitPolicy guide to follow after gateway walkthrough

[jasonmadigan]

Kuadrant/docs.kuadrant.io#14

Some copied and modified guides as jumping-off points from the multicluster gateway walkthrough, based on:

• https://docs.kuadrant.io/kuadrant-operator/doc/user-guides/simple-rl-for-app-developers/

Main thing changed here is:

• Updated setup, with the view that you've already run the quickstart+gateway walkthrough guide, so you've got Gateways, TLSPolicy+DNSpolicy already setup
• Rest of the guide is largely as-is, apart from some changes owing to the fact that you'll have working DNS

Steps to test

• After running quickstart, setup your env to use kuadrant 0.4.0-rc1 catalog source - see https://gist.github.com/jasonmadigan/bde64d4967fdbb740fd8eb876f2579dc. This will pull in RLV2.
• Run through the revised multicluster gateway walkthrough (important, because it created a wildcard gateway listener that we use in the auth + rl guides).
• Step through the RL how-to guide

Follow-on

Create a similar AuthPolicy guide (parked for now in 14-ap-guide)

@guicassolato hopefully gives you an idea as to what I'm at. Can incorporate your new guide once you think it's in a good place

Leaving this here for someone else - here's how to use a pre-release operator catalog to test preview service protection addon stuff:

TODO: New Nav in a docs.kuadrant.io PR.

Would like a final @guicassolato step through too for sanity, but appreciate that may be hard to do this week

I stepped through the guide and everything worked as expected. Some small comments inline.

thanks @laurafitzgerald - have added

After chatting with @maleck13 a bit, I think we're going to land the AuthPolicy guide a little later when v1beta2 is available, so I'll split this PR in two and land the RLPV2 bits first.

[jasonmadigan]

Have now split this up so this only incorporates a RLV2 guide - a new authpolicy guide can come when we ship the 0.5.0 Kuadrant operator.

I've parked the AuthPolicy guide as it is in 14-ap-guide on my fork.

Might be worth a note here that this limit is per cluster hosting the echo service
