Enable tests for protection rules based datasources and resources

[bhati-pradeep]

Updates:

• Set description from api response in data_source_protection_rule
• Update test_config.json and main_test.go to have fields for local_az and destination_az (availibility zones) based required uuids which will be used in tests related to protection rules.
• Skip protection rules based data source and resource tests as per the env variable : PROTECTION_RULES_TEST_FLAG
• Create two protection rules before using nutanix_protection_rules data source in tests.
