Add support for docker additionnal args

[FJEANNOT]

Hi there,

A little unsolicited PR.

I'm using this to get GPU acceleration using ClusterODM by passing "--gpu all", so i thought I could share it, in case someone else needs it.

I've cleaned this up, and added it for every provider, but be aware that it was only tested with AWS.

Hey thanks for the PR! Indeed it would be useful to have the ability to set --gpu all.

• Would it be possible to have a dockerGpu or gpu boolean field rather than manually overriding args in the settings?
• I think you've tested this and it didn't crash, but the --gpu all parameter is not being passed in the correct order to the docker command (for AWS also). warning: Unrecognized flag gpus

Ha yes good catch, it should be before the docker image. I've made the changes

Looks good, thanks @FJEANNOT !
