Add annotation to exclude containers from injection.

[StefanHauth]

Description

Allow to exclude containers from injection based on their names with annotations on Dynakube or pod level.

How can this be tested?

Deploy a Dynakube and an application.
Add annotation container.inject.dynatrace.com/<containername> = false to exclude app containers from injection.
Check that code modules are not injected into containers.
