Update source code `Kind` to `Type`. It's only changes within our code. Changes to yaml tag (that will affect users) will be done in later PRs. This is a breaking change since it updates telemetry's span attribute from `source_kind` to `source_type`. Related #817 Future updates will include: * Updating a preprocessing function to convert config file from v1 to v2 * Update unmarshal function for ToolsFile to convert config file (test will fail since the yaml tag is not yet updated). * Update yaml tag (test will pass).
