Docker changes for version 10+

[ThomasB]

Hi,

are the docker changes to split the one volume into 3 really neccessary?

I have a custom installation with docker swarm mode, so I need to adapt the changes.

Hi Thomas,

Before, we used a volume for all Espo files. Now, only the following directories are in volumes: client, custom, data, public. While the EspoCRM is in the containers. The client and public directories are copied from the Espo container to the volume on start.
