chown and chmod in docker-entrypoint.sh can take a long time to complete, allow disabling the call

The chmod and chown call in docker-entrypoint.sh can take a very long time to complete if the files directory is big.
We noticed the issue when preparing a new deployment with files hosted as an Azure File Share with dozens of GB of files.

An environment variable should be added to disable running the chown/chmod.

Hey @yosifkit i know this issue is somewhat old, but how does #136 fix an issue with lots of files from an old redmine installation for example ?
It looks to me as if the find runs on every start ? shouldnt this be only necessary on the first run ?

Our install has files starting from 2014, most issues are generated from email and contain the .eml and all attachments separately ... which results in currently 996388 files

i think the option to skip the find/chown/chmod would be a good addition

Creating a new issue, because its not the only issue with _fix_permissions i think
