Docker file changes, shell script changes

Some Big Changes!

Motivation

The main motivation here is to make the docker system more flexible, this means allowing users to build images themselves using whatever base image and version of Blender they wish. It also means allowing for using development branches of the addon inside a running container via a bind mount. The really helps include docker images in our development cycle as currently the only way to test if new code in the addon works in a container is to publish the addon live, and then pull it into a running container.

Changes

Dockerfile

• Make it possible to build a functioning Blender/Crowdrender image from a base image like debian/Ubuntu/Nvidia etc. Optinos are available to choose the versino of Blender to install into the image.
• Removed the 'local' option, this is replaced by passing through the following options as env vars to the running container; persistent; token; secret; machine_uuid

Shell scripts

• Support the new --override-machine-uuid option for crowdrender.
• Allow the addon to be mounted from a bind mount so that a development branch of Crowdrender can be used inside a container. This is via a new shell script run_dev_env.sh
• Modified the install_addon script so that its possible ot run crowdrender from a bind mount instead of downloading a version from discovery.

Other Chnages

• Added a dockerignore file
• Updated the make file to support docker building with other veresions of Blender.
• Updated readme
• Updated the github actions file to include options for building images with specified versions of blender. Separately the secrets for the docket name and token have been changed on github to point to the new crowdrender docker hub.

Hi @zocker-160, I've just pushed commits to this branch/PR. Would really appreciate if you can let me know what you think and if we can merge. I really would like to get these containers back in use, since we've not updated them in ages, I think people are less likely to use them since Blender has moved on and is about to move to V4.0.

I think the changes I've made will help, I've tested GPU support on Docker Desktop in windows with a new docker file that is based on the original. All works well.

Cheers!

Seems to be working from my short testing, merging now after our conversation on Slack, but more changes will be needed (especially in the Readme which is kinda a mess IMO).
