Suggestion: Move binary files in build directory to avoid increasing git repo size over time

[g7morris]

Just recommending that we consider moving https://github.com/Islandora-Devops/isle-dc/tree/development/build/demo-data to a separate git repo to avoid increasing git repo size over time and potentially increasing git clone or other deploy times considerably.

With every branch created, merged etc, over time these files are replicated a lot and I'm seeing this trend occurring already.

37M     build
8.0K    CONTRIBUTING.md
12K     docs
4.0K    LICENSE
24K     Makefile
20K     README.md
4.0K    sample.Dockerfile
8.0K    sample.env
8.0K    scripts
84K     secrets

While the build directory is currently 37M the entire repo is now 89M. The "extra" 52M is coming from this unnecessary replication.

We could simply create a new git repo, move the build directory there and update any scripts to call from it as part of the demo process.

Additionally we can use a tool like bfg-repo-cleaner to remove all binaries from all branches and commits which should reduce the size dramatically.

Happy to help further with this as needed.
