Rerun failed tests

[darkknight13]

Apologies in advance if these changes seem extensive;

Changes Made:
Added classes CQLTest, CQLTests, CQLTestResult, and CQLResults to encapsulate functionality related to CQL tests, test results, and test runs.
Modified the script to accept command-line arguments for running test based on previous run status.

Classes:

• CQLTest: Represents a single CQL test, with methods for loading configuration, preparing the test, saving the test configuration to a file, running the test against an API, and generating a checksum for the configuration.
• CQLTests: Represents a collection of CQL tests, with methods for adding tests, running all tests, and caching test results.
• CQLTestResult: Represents the result of running a single CQL test, with methods for computing the result and saving it to a file.
• CQLResults: Represents the overall results of running CQL tests, with methods for summarizing the counts, converting results to JSON format, and saving results to a file.

Functions:

• loadTestsFromCache(tmpPath, testStatus): Loads tests from cache based on test status.
• loadAllTests(tmpPath, quickTest): Loads all tests, optionally loading only one group or one test set for testing.

Command-line Arguments:
-status=: Specifies the test status to run.
