Infrastructure Manager - create initial project structure

[akgalwas]

Description

Create a minimal structure for Cluster Inventory Infrastructure Manager.

Acceptance criteria:

• Initial project scaffolding - @Disper
  • Initializes cluster-inventory using kubebuilder  #12
  • Adds output of create api --group clusterinventory --version v1 --kind Cluster command #15
  • renames DOCKERFILE to Dockerfile to fix make docker-build #20
• Make test should print output for few test cases, they should run in less than 30 seconds  #16 - @Disper
• GitHub action test runner #17 - @Disper
• Adds initial content of the project README #21 - @Disper
• add cluster-inventory build and pull jobs test-infra#8877 - @Disper
• CRD structure prepared #24 - @akgalwas
• Simple controller implemented. It should print CR name, when a CR is created, or deleted.
• Controller can be deployed with make deploy command - @akgalwas
• renaming the project to the final name
  • renames build jobs from cluster inventory to infrastructure manager test-infra#8894
  • rename repo content to infrastructure manager #29

Stretch:

• consider a /hack directory with convenient Makefiles for local/ci
• Configure linter github action job #7
• Security scans
  • security tools https://github.com/search?q=repo%3Akyma-project%2Ftest-infra%20application-connector-manager&type=code
  • Also consider new go lang vuln check
• adjust CODEOWNERS file in cluster inventory #25
• reuse compliance
• Consider e2e smoke test
• markdown link checker

Reasons

In order to kick off the implementation we need to define the code structure, create pipelines. We also need to define the interface for Kyma Environment Broker that is supposed to create Cluster CRs.

Stretches created as follow-ups:

• Enable markdown link checker #34
• Infrastructure Manager - Configure security scanners #33
• Infrastructure Manager - Dynamic kubeconfigs e2e test #35
