Updated patch:
- Add optional Hadoop configuration override for WorkspaceConfig

> Key: DRILL-4603
> URL: https://issues.apache.org/jira/browse/DRILL-4603
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - Other
> Reporter: Venki Korukanti
> Assignee: Venki Korukanti
> Fix For: 1.7.0
>
>
> Currently FileSystemPlugin is hard to extend, lot of logic for creating
> component implementations ({{WorkspaceSchemaFactory}}s, {{FormatCreator},
> defining default workspaces and configuration (implicit to FileSystem
> implementation)) are hard coded in constructor.
>
> This JIRA is to track
> * refactoring the FileSystemPlugin to allow custom component implementations
> (Configuration, WorkSpaceSchemaFactory, FileSystemSchemaFactory or
> FormatCreator).
> * Share a single Hadoop {{Configuration}} object to create new
> {{Configuration}} objects. Creating a new {{Configuration}} without an
> existing copy is not efficient, because it involves scanning the classpath
> for *-site files.
