tests: move plugin tests to src/plugins/*/test
- Relocate plugin tests for 'make test' into src/plugins/*/test so that plugin test cases are co-located with the plugin source code. Type: refactor Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Change-Id: I503e6a43528e14981799b735fa65674155713f67 Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
