Exorcist & Warehouse Integration Plan

This is a meta-issue to outline the order in which PRs should be merged, and what (if any) work needs to be done.

In general, my intention is to write user-facing docs for each item, request sign-off by @ethanholz (at minimum, to ensure the code is fully handed off), then consider these ready for merging.

new features, non-breaking changes: Epic #2113

• #1864: needs user-facing docs, but otherwise is unblocked
• #1833: downstream of #1864, example exorcist implementation that uses a filesystem warehouse and therefore is not blocked by https://github.com/OpenFreeEnergy/gufe/pull/753.
• https://github.com/OpenFreeEnergy/openfe/pull/2155: usability changes needed for # 2114
• PR #2114: adding results handling to the above proof-of-concepts

CLI functionality:

• PR #2156 : status checking, pretty simple task db query
• #2164: CLI results gathering - this might require some coordination with ResultsNetwork to avoid duplication of effort
• #2165: rewrite example warehouse planning CLI to match new API once # 1864 is merged.

new features, breaking changes:

• https://github.com/OpenFreeEnergy/gufe/pull/753: these are the breaking changes.
• #2073: After https://github.com/OpenFreeEnergy/gufe/pull/753) are made, we can then go back to the code touched by #1864 to take full advantage of the new context & storage objects. This will be a breaking change in openfe.
