dovetail tool: add unit test into script unittest.sh

1. Since JIRA: DOVETAIL-55 has been merged, unit tests can't pass without
   load_config_files().
2. Fix the bug by adding load_config_files().
3. Add run_tests() into script unittest.sh to include all unit tests in
   tests/unit.

JIRA: DOVETAIL-149
