We need to find the best way to disable ccache (which must be disabled in Bazel)
especially for the environments where it is not possible to remove (sudo apt-get remove).

Scope

1. Experiment and suggest ways to disable ccache
   • Note that CCACHE_DISABLE=1 does not work
2. Describe the best way to disable ccache
3. Detect ccache in the code (tools.bzl?)
4. Update documentation and code
   • Add description to ccache detection code (tools.bzl?)
   • README
   • CONTRIBUTING (if needed)

DoD (Definition of Done)

• Detection is added
• Documentation is updated
