Support to filter CI Validation builds
To select CI validation builds it is useful to have a tag to use as filter.
The CI reporter script will send this tag using the attribute: validationsuite
This attribute will be optional
The values of the "validationsuite" attribute will be included in the left panel of the CI web app in a list named "Validation suites" similar to the "Test suites" one.
Selecting an element from the list, the CI web app will show only the CI builds associated to the selected validation suite.
