Rename the services folders for more precise and less redundant names & rename the docker-compose/k8s services accordingly

Changing the folder names for a better understanding, and having less redundant services/folder names:

• consent-webservice → consent-endpoint
• consent-commandhandler → consent-cmdhandler
• consentsigning-webservice → signing-endpoint
• consentsigning-commandhandler → signing-cmdhandler

Changing the docker-compose services names for more informative names:

• pulsar → platform-pulsar
• mongodb → platform-mongodb
• pdp → accesscontrol-pdp
• pip → accesscontrol-pip
• consent-webservice → cme-consent-endpoint
• consent-commandhandler → cme-consent-cmdhandler
• consentsigning-webservice → cme-signing-endpoint
• consentsigning-commandhandler → cme-signing-cmdhandler
