Allow to set file limits via env-file

[xvybihal]

Do you want to request a feature or report a bug?
This is feature request.

What is the current behavior?
Currently the limits are hardcoded in container inside of conf files. For example /etc/onlyoffice/documentserver/default.json file.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
See #354 for suggestion how they can be changed.

What is the expected behavior?
My suggestion is to add the ability to set those limits via env-file, instead of mangling .conf and .json files inside of the container. I propose names:

NGINX_CLIENT_MAX_BODY_SIZE
MAX_FILE_SIZE
MAX_DOWNLOAD_BYTES
INPUT_LIMIT_UNCOMPRESSED_DOC
INPUT_LIMIT_UNCOMPRESSED_XLS
INPUT_LIMIT_UNCOMPRESSED_PPT

So the settings could be done using environment variables like this:

NGINX_CLIENT_MAX_BODY_SIZE=100M
MAX_FILE_SIZE=104857600
MAX_DOWNLOAD_BYTES=104857600
INPUT_LIMIT_UNCOMPRESSED_DOC=50MB
INPUT_LIMIT_UNCOMPRESSED_XLS=300MB
INPUT_LIMIT_UNCOMPRESSED_PPT=50MB
