Add Pre Commit Hooks and Editor Config

[kdvalin]

Description

Adds an .editorconfig to help enforce code standards.

Adds pre-commit framework to lint committed files. This works in addition to any pre-installed hooks (like Red Hat's leak checker)

Before/After Comparison

Before

Code style was not enforced, required manual review to catch problems.

After

Code style is automatically set by .editorconfig, more advanced linting issues are caught by the shfmt pre-commit hook.
