Merge ~mthaddon/charm-k8s-mattermost/+git/charm-k8s-mattermost:image-build into charm-k8s-mattermost:master

[Tom Haddon]

Add Dockerfile to main charm project, now it can be ignored from charm builds via .jujuignore

Add Dockerfile to main charm project, now it can be ignored from charm builds via .jujuignore.

Things we'll need to update once this has landed:
 - https://charmhub.io/mattermost/docs/plugins-custom-images to point to the correct Dockerfile location
 - OCI Recipe build https://launchpad.net/~mattermost-charmers/charm-k8s-mattermost/+oci/mattermost/+recipe/mattermost to use the correct branch
 - Internal wiki documentation on how to build custom image for internal usage
