Add mutex-like waiting functions to the entrypoint.sh
The function wait_for_neo
should contain a place where all wait functions are started in the background and give a corresponding status about the state of their task. Then it should be checked if 7687
and 7474
are open and active. Alternatively, it should also be possible to check whether dbas_db
is active on port 5432
. This is supposed to be an implementation of mutexes in bash. It should be achieved that one long wait time affects the others.
