CMP-4119: Use OCP4 CIS control based referencing

[yuumasato]

Description:

• Enable control based references for OCP CIS v1.9.0.
• Removes OCP4 CIS from the rules.

Rationale:

• By using the control based referencing we don't need to maintain them in the rules anymore.
  They are automatically injected into the rule during build time.

Review Hints:

• Requires CMP-4119: Add support for CIS v1.7.0 and CIS v1.9.0 references compliance-operator#1104 for CO to show CIS versioned Annotations.
• Check that the OCP4 DS has CIS references.

Note

After feedback that older versions of CIS profiles are not that useful, I have changed this to add references based only on the latest version.

I have dropped support for multiple CIS reference versions.
