#4619 [Housekeeping] Add CI tests to flytekit repo: plugins should be importable with flytekit dependencies only Issue created by cosmicBboy ### Describe the issue The purpose of this issue is to enforce the following convention in flytekitplugins: "I should be able to

import flytekitplugins.<plugin>

with only flytekit dependencies. This ensures that we use lazy module loading in the plugins (see flyteorg/flytekit#2049). ### What if we do not do this? When new plugins are introduced (or existing ones are extended) contributions can break this convention when new dependencies are added. ### Related component(s) No response ### Are you sure this issue hasn't been raised already? • Yes ### Have you read the Code of Conduct? • Yes flyteorg/flyte
