Could you make it so that you could just lay down files, attach storage and start the service?
Also, clustering (active/active) word be awesome.
There are a few options for configuration management and automation.
The installer[1], web setup[2] and almost everything in settings/admin/provisioning can be done via a config file, script or REST call[3].
There are a few 3rd party modules for config management tools available that make use of this:
Chef: https://github.com/bflad/chef-stash
Puppet: https://forge.puppetlabs.com/thewired/Bitbucket
We also provide a docker image that may be of interest: https://hub.docker.com/r/atlassian/bitbucket-server/
As for clustering, Bitbucket Data Center[4] provides the same self-hosted functionality as Bitbucket Server for 500+ user tiers, with active-active clustering for performance at scale and HA, as well as Smart Mirroring for distributed git read performance.
Feel free to email me (rbarnes@) if you have feedback on how these options work for you.

For Clustering - any reason you need active/active? We have mirroring[1] which (from our chats with most of our customers) is what people prefer.
