Install community modules (not managed)

[pbochynski]

Description
Modules provided by user (module template installed manually by the user) should be applied directly in the cluster (see PoC code: https://github.com/kyma-project/community-modules/blob/804dea3f6cc764a2a952b66bdf446c7c7d01bd92/k8s.js#L7).
You can distinguish user modules by checking managed-by label (not yet implemented).

Acceptance Criteria

• on community modules list add button Add community module
• show Add community module view similar to previous Add module
• all of the previous functionalities must work (channel, versions, icons, documentation, etc)
• parse module templates that don't have managed-by label and resource in spec.manager don't exist and show on view
• no need for managed checkbox
• channel might be empty
• to install take data from .spec.resources from ModuleTemplate and deploy it on the cluster (raw files or artifacts from release)
