Gloo edge improvements

[antonioberben]

• Remove troubleshooting Tip

• Lab2: Create unauthenticated RateLimit for unauthenticated users

• Lab2: Add another Ratelimit for authenticated users based on a new claim like subcription (values: gold, platinium, etc).

• Lab6: For the AuthN scenario, it needs to be moved to Lab2.

• Lab6: Remove the extractor for the id token since it is already taken before.

• Improve WAF sample. Block a huge payload with POST to bookinfo for the case of unauthenticated users

• Improve WAF sample. Add client-agent check

• Add to response transformations. Take a header from the request and add it into the response.
  TODO: The docs are wrong. It's missing identation. Besides it does not work. Spike on it.

• Improve response transformations. Take the 401 and transform the body in the response.

• Add something with regex

transformationTemplate:
                           passthrough: {}
                           extractors:
                               originalClientIpAddress:
                                   header: 'x-forwarded-for'
                                   regex: '([^,\n]*).*$'

• Move delegation after LAB1. Delegate to different routeTables to different teams /secure with reoutetable1 to be managed by team1. Keep the route / at the VS level to show that we can also keep things in the VS

• Move RT to a specific namespace like team1 so they can see it can be in a different namespace.

• Use label selectors for the RT so we can show that the name is note totally required

• Lab6. Remove the extractor for the id token since it already taken before. → use the extauth > authconfig > oidc > headers > idTokenHeader to forward it upstream
