feat(framework.cucumber): Allow multiple tags on cucumber tests.

Motivation:
Support for multiple tags on the cucumber test execution, to be able to filter with more complex expressions the scenarios to run.

How to use:
cucumberOpts: {
    tags: '@dev'
}

or

cucumberOpts: {
    tags: ['@dev', '~@ignore']
}

More information on tags:
