Add Honeycomb TAP interface test

JIRA: CSIT-75

 - add test suite for TAP interface management through Honeycomb
 - add keywords required for TAP interface tests
 - move Honeycomb suite setup and teardown to new __init__ file
 - cleanup unused imports in Honeycomb test case files
 - modify "...should be empty" keywords to allow more reuse
