Brief summary of the bug. What is it ? Where is it ?

Sharing in the CCSM docker-compose file is disabled, we should remove that manual setting to fallback to the default (true).

Variable in docker-compose.ccsm file :

CAMUNDA_OPTIMIZE_SHARING_ENABLED=false 

Expected result:

It has to default enable. 

 CAMUNDA_OPTIMIZE_SHARING_ENABLED=true

OR

Just remove setting that environment variable, to use whatever the current default is.
