Changes for tacker-horizon integration tests

The tacker-horizon integration test framework has been implemented[1]
While adding integration test cases a selenium exception [2] was
observed for test cases under directory [3].

Tacker-horizon UI Details:

* Most of the Horizon plugins, such as manila-ui and vitrage-dashboard
  support integration tests, these plugins reside under "Project" tab.
* Whereas, tacker-horizon, mistral-dashboard are horizon plugins which
  have their dashboard anchored directly at the top-level alongside
  "Project" tab.
* The tacker-horizon has two-panel groups,
   * VNF Management
   * NFV Orchestration
* The "VNF Management" is a default panel and remains expanded in NFV
  dashboard, whereas "NFV Orchestration" is collapsed initially.

Selenium Exception Details:

* The horizon framework reports an exception
  ElementNotInteractableException, while opening pages under
  "NFV Orchestration" panel group.
* This error occurs when an element is not clicked or it is not visible
  yet.
* The menu item expansion code in the horizon integration framework
  expands only those menu items (level first, second or third) if only
  the previous menu item at the same level was expanded earlier.
* For example, in order to open a page[4] under NVF Orchestration panel
  group, the framework collapses "Project" tab and clicks "NFV"
  dashboard.
  But it never expands "NFV Orchestration" panel as in second-level no
  such transition occured hence it remains collapsed. So test case fails
  to find desired page.
  On the other hand, test cases for pages under "VNF Management" succeed
  as the panel group by default remains open.

This patch adds functionality to detect collapsed menu items and expand
the items.
