Replace language-container deployer with the common implementation in python-extension-common

[tkilias]

We extracted a common implementation for the language-container deployer to the python-extension-common repo. We need to replace the implementation with common by importing and configuring it.

Tasks:

• language_container_deployer.py can be removed, because it is completely implemented in python-extension-common
• language_container_deployer_cli.py can be removed, because it is completely implemented in python-extension-common
• deploy.py needs its imports changed to python-extension-common
• sme_language_container_deployer.py needs its imports changed to python-extension-common
• We probably need a test, that at least checks, if the path defined sme_language_container_deployer.py work with deployer cli and SmeLanguageContainerDeployer
