Extracted all global parameters into functest_constants.py

JIRA: FUNCTEST-533

1. Extracted all global variables into functest_constants.py and updated all affected areas accordingly
2. Used os.path.join to replace '/'  to come up with the path for better cross-platform support and improve the path accuracy
3. Removed unused variables
4. Updated the hardcoded path in Dockerfile by using variable reference
5. Removed "/" ending from all path variables
6. Updated the unit test
