feat(run_tests.sh): install operators as needed by the tests.

[razvan]

Install tests as needed by the operator test suite.

This makes the operator installation the responsibility of the test suite.

Advantages:

• PR tests can now reference opreators from other PRs.
• Only install the operators that are needed for by the test suite.
• Running the integration tests from GH actions do not require workflows to know
  about the operator installation.

Operator installation is optional and only done if a file named tests/release.yaml is found.

Here is an release.yaml example for the trino-operator

# Contains all operators required to run the test suite. --- releases: # Do not change the name of the release as it's referenced from run_tests.sh tests: releaseDate: 1970-01-01 description: Integration test products: commons: operatorVersion: 0.0.0-dev secret: operatorVersion: 0.0.0-dev listener: operatorVersion: 0.0.0-dev zookeeper: operatorVersion: 0.0.0-dev hdfs: operatorVersion: 0.0.0-dev hive: operatorVersion: 0.0.0-dev opa: operatorVersion: 0.0.0-dev trino: operatorVersion: 0.0.0-dev

Looks good, though haven't tried to test the workflow yet.
