Add module skeletons

- Remove `suite` and `case` which seems redundant at the moment
- Rename `qtip.spec` to `qtip.loader` since the class loads spec
- Add driver `sample` which will generate random performance data
- Add collector `logfile` which will collect result from log files
- Add reporter `console` which will print report to console
- Add exception classes

See updated class diagram in https://wiki.opnfv.org/display/qtip/Design
