This change causes the linter to be a bit more complainy. The hope is
that this will cut down on some of the more pedantic issues being caught
in code reviews, and thus reduce the overall time a change spends in the
review process.
This change includes various changes to the codebase to bring it up to
the new standards.
Change-Id: I570d304bca5554404354f972d8a2743279a0171b
Each of these include an option for --current-context that set or retrieves
the curret context
This patchset mainly creates the cmd/config and pkg/config require additions
Also includes a fync getCurrentContext(<CLUSTERTYPE>) in the config pkg
that other modules should rely on.
Introduces new ErrMissingConfig and ErrConfigFailed types been used by
set-context, will decimate through get/ and set/get cluster after this is
reviewed.
