Description

Once https://github.com/jupyter/repo2docker/pull/595 is merged and we have some experience with it, we should investigate whether we can use PackageCompiler.jl during the build step to compile a custom sysimage that includes all the packages in the Project.toml. That custom sysimage would then be stored in the docker file. This has the potentially to make things a lot more snappy because we could probably get around a fair bit of JIT compiling.

Research direction
This issue builds on PR #595 which adds basic Julia support. Investigate using PackageCompiler.jl to create a custom sysimage with all packages from Project.toml during Docker build. Look at the build scripts in repo2docker (e.g., Dockerfile or buildpacks) to find where to integrate compilation. Assess performance improvements and potential trade offs with build time.
