Load STIG standard after ACOMMONS-11 is done

[andrei-epure-sonarsource]

Next week, a new version of analyzer commons will be added via https://sonarsource.atlassian.net/browse/ACOMMONS-11 to enable the import of a new security standard.

As part of the SQ plugin hardening sprint, we should update Analyzer commons and call the metadata API.

Check the PR for adding support for ASVS standard - should be the same thing as in #5941
Edit by Mary: Functionality of this PR is no longer valid. We use the common functionality to add security standards by sonar-commons-io. Should be enough to update the package sonar-commons-io and add tests.

• Add a check for the SonarQube version (it will be shipped in 10.7 in September). On SonarCloud it's already supported.
• Tests are in CSharpSonarRulesDefinitionTest .

sonar-commons should be released today or tomorrow; however, we also need this PR to be merged SonarSource/rspec#4098 in order to be able to close this issue.
