Create installation and usage guides

[excieve]

There's a wide variety of ways this group of charts can be installed:

• Tyk Pro
• Tyk Hybrid
• Everything mentioned with gateways configured by Tyk ingress controller
• Tyk CE (with headless ingress controller)
• Service Mesh

These options service different needs and should be guided separately as the existing readme causes a lot of confusion. It should also be clear which ways are stable, which experimental, etc. There should be full examples of ingress controller usage patterns.

All chart options must be documented.

This should be kept open.

You can use this shell script I cooked up here to launch Tyk-CE and Tyk-Operator on k8s cluster without any issue. Hopefully someone finds this useful.
