Update repo structure for base vs project cluster components

[nikimanoledaki]

• Create a falco namespace that will contain the Falco deployment + demo workload.
• Change repository structure to have:
  • clusters/projects/<cncf-project> for CNCF projects such as Falco etc. We can change this further in the future if needed.
  • clusters/base/<base-components> for Kepler, Prometheus, etc.

@nikimanoledaki What about using clusters -> projects -> CNCF project for the naming strategy?

Apps is also good but I think projects is clearer for our use case.

@rossf7 very good point, renamed!
