Provide ability to just run existing image template

[stephenmahood]

Currently the action takes either the local JSON or the action parameters and creates and uploads an image template and then runs it. We'd like to manage our image template definitions along with other ARM template deployments and only use the action to initiated the run. Using the image-builder-template-name parameter it would be good to check if there is a template which already exists by that name and use it rather than attempting to re-submit the same template.

Effectively we'd need a test here to see if the image template already exists before trying to put the image template

@stephenmahood I was thinking of doing a couple of things.
(I do not work for MS just trying to be active in the community)

Part of this sounds interesting.
I think the image builder needs to allow image template update
https://docs.microsoft.com/en-us/cli/azure/image/builder?view=azure-cli-latest#az-image-builder-update
Updating an image builder templates is currently unsupported.

I can see the benefit if the template has not been updated. Would something where If the template name and a md5 hash of the template matched work as well. This way if there are no updates to the template but you want to rerun it you could. Otherwise, it looks like you would have to delete and recreate which would just add more time to the process. There is something about using --defer but that sounds like something that should work but might not work as constant as one would hope.
