[Feature] inject Python agent automatically in SWCK

• [X] I had searched in the issues and found no similar feature requirement.

Description

Since https://github.com/apache/skywalking-python/pull/159 is merged, we have Docker image for SkyWalking Python agent and non-intrusive way to install the agent, it would be perfect if we can also enhance SWCK to make it possible to inject the Python agent automatically when Kubernetes annotation is specified.

Use case

When users label a Kubernetes Pod with a special annotation, for example, swck-java-agent-injected=true, SWCK can automatically inject the Python agent to the application Pod, hence the users don't even need to modify their Docker image.

Do I wait the Java PR to be ready first? In case something can be reused. Looks like a very big feature there base on the LOC.

@wu-sheng I would try my best to proceed soon, so that hopefully we could go to 1.0.0 in early March. Sorry for the delays, I had to focus on my graduate research on service mesh recently.

Service Mesh is good to learn :)

Hi @Superskyyy , @fgksgf is interested in this issue and he has enough available time recently so I just suggested him to take a look at this. Please comment here if you've already started, in case.

Hello! Actually, I already started implementing this one last week, I was planning to finish it this month and go for the 1.0.0 milestone. Can we see if there's another work that is suitable for @fgksgf?
