This release implements the following changes:
- Meta properties for a plugin are now available via the connection object.
`self.connection.meta.name/version/description/vendor`

- Steps (actions/triggers) now auto-log their identity when ran.
Example: `rapid7/IPStack:1.0.0. Step name: lookup`

- Plugin tests no longer validate their input. Addresses a regression introduced with gunicorn/webserver mode implementation.

This release addresses the following:
- Webserver mode now throws a 400 Bad Request message when a value other than "test" is found in the test position of the URL route.
- Legacy test functions (actions/triggers) now ignore validation on output.
- Updated documentation in the SDK to direct users to the proper URL route for testing in webserver mode.

This release updates the deprecation notice as well as changes the body of the test function from raising a NotImplementedError to `pass`.

This release adds support for test functions in connection files. When a test function is declared in the connection file any test functions present in actions/triggers will be ignored.

A test function declared in the connection file will _not_ have it's output validated against any ran action/trigger, allowing for a generic test function.

Switches BaseException for Exception, adds additional presets.

Add ConnectionTestException for use in connection tests
