Improve the development workflow with the new build system

- update the ctest environment to output failure messages
	- fyi: test output is already captured in './Testing/Temporary/'
- create a separate docs target
    - force install/package to rebuild the documentation since we have no dependency analysis
- create a new clean-heka target to sync the Go workspace and repository tree.
- update docs
Update the configuration due to the last merge with dev

- remove the hard coded /tmp path
