Add an option to run specified browser type and mode for e2e tests execution

[avozicov]

Expected result:

• Run e2e tests with the specified browser and mode defined under e2e component in .recink.yml

  
  pattern:
    - /.+\.e2e\.js$/i
  screenshot:
    enabled: true
    take-on-fail: true
    path: './tests/e2e/screenshots'
  browsers:
    - firefox --headless ```  - in this case Firefox browser is expected to run e2e tests instead of Chromium (which is default for recink)

@eistrati @avozicov from the terraform module we do not have access to the e2e params, how can we workaround this?

ec2:
  root: './ec2'
  terraform:
    version: 0.10.0
    plan: false
    apply: false
    destroy: true
    test:
      plan: './ec2/tests/'
      apply: './ec2/tests/'
      browsers:                       <= something like this?
        - firefox --headless          <= something like this?

@ddimitrioglo as discussed this morning, we agreed on the following setup:

Test Passed Acceptance Criteria:

• There should be a possibility to define browser type and mode for test component configured under recourse module
• In this case specified browser should be executed instead of the default one and browser mode (--headless) should be also applied if specified

Configuration example with the specified browser type and mode
