Title: Deprecated a few methods

* `TangUtils` should be provided by Tang, not REEF
* `EnvironmentUtils.addAll()` should be provided by Tang
* `EnvironmentUtils.getReefHome()` makes no sense any more, given that REEF isn't assumed to be "installed"
* `EnvironmentUtils.getClassLocationFile()` was never used and is merely a shorthand for JDK functionality.
* Deprecated `EnvironmentUtils.getVersion()` in favor of `REEF.getVersion()`
