* Only write config in environment-to-ini if there are changes
Only write the new config in environment-to-ini if there are changes or the
destination is not the same as the customconf.
Fix#15719
* Add environment-to-app.ini routine
* Call environment-to-ini in docker setup scripts
* Automatically convert section vars to lower case to match documentation
* Remove git patch instructions
* Add env variable documentation to Install Docker
* Add contrib/environment-to-ini
This contrib command provides a mechanism to allow arbitrary setting
of ini values using the environment variable in a more docker standard
fashion.
Environment variable keys should be structured as:
"GITEA__SECTION_NAME__KEY_NAME"
Use of the command is explained in the README.
Partial fix for #350
