Summary:
Python 2 only needs to be supported for the sake of old documents and formulas. This doesn't apply to the separate sandboxes that parse files for imports. Using Python 3 only allows using newer libraries and library versions. In particular, the latest version of openpyxl doesn't support Python 2. This will also make it easier to make other similar changes in the future, such as replacing messytables with a modern library. See https://grist.slack.com/archives/C0234CPPXPA/p1661261829343999?thread_ts=1661260442.837959&cid=C0234CPPXPA
The latest openpyxl is better at handling a particular edge case with broken dates in Excel, but still doesn't quite do what we want, so we monkeypatch it. Discussion: https://grist.slack.com/archives/C02EGJ1FUCV/p1661440851911869?thread_ts=1661154219.515549&cid=C02EGJ1FUCV
Setting `preferredPythonVersion` to '3' in SafePythonComponent ensures that JS always creates import sandboxes that use Python 3. Within Python, a module used by all imports will raise an error in Python 2. Python unit tests of imports are now only run in Python 3, using the `load_tests` protocol of `unittest`.
Test Plan: Mostly existing tests. Added another strange date to the Excel fixture.

Summary:
Based on https://github.com/gristlabs/grist-core/pull/251. It may not look like it, but there's very little going on in this diff:
- Tweak the DATEVALUE doctest for Python 2/3 compatibility.
- Mirrors the PR's changes to requirements3.txt in requirements.txt, i.e. make the same dependency upgrades in Python 2.
- Make the same upgrades in the thirdparty folder for the Python 2 nacl sandbox.
Test Plan: Updated one doctest for dateutil. Checked changelog of sortedcontainers. html5lib is only used by messytables and isn't actually relevant.

Summary:
Use openpyxl instead of messytables (which used xlrd internally) in import_xls.py.
Skip empty rows since excel files can easily contain huge numbers of them.
Drop support for xls files (which openpyxl doesn't support) in favour of the newer xlsx format.
Fix some details relating to python virtualenvs and dependencies, as Jenkins was failing to find new Python dependencies.
Test Plan: Mostly relying on existing tests. Updated various tests which referred to xls files instead of xlsx. Added a Python test for skipping empty rows.

Summary:
* Moves essential plugins to grist-core, so that basic imports (e.g. csv) work.
* Adds support for a `GRIST_SANDBOX_FLAVOR` flag that can systematically override how the data engine is run.
- `GRIST_SANDBOX_FLAVOR=pynbox` is "classic" nacl-based sandbox.
- `GRIST_SANDBOX_FLAVOR=docker` runs engines in individual docker containers. It requires an image specified in `sandbox/docker` (alternative images can be named with `GRIST_SANDBOX` flag - need to contain python and engine requirements). It is a simple reference implementation for sandboxing.
- `GRIST_SANDBOX_FLAVOR=unsandboxed` runs whatever local version of python is specified by a `GRIST_SANDBOX` flag directly, with no sandboxing. Engine requirements must be installed, so an absolute path to a python executable in a virtualenv is easiest to manage.
- `GRIST_SANDBOX_FLAVOR=gvisor` runs the data engine via gvisor's runsc. Experimental, with implementation not included in grist-core. Since gvisor runs on Linux only, this flavor supports wrapping the sandboxes in a single shared docker container.
* Tweaks some recent express query parameter code to work in grist-core, which has a slightly different version of express (smoke test doesn't catch this since in Jenkins core is built within a workspace that has node_modules, and wires get crossed - in a dev environment the problem on master can be seen by doing `buildtools/build_core.sh /tmp/any_path_outside_grist`).
The new sandbox options do not have tests yet, nor does this they change the behavior of grist servers today. They are there to clean up and consolidate a collection of patches I've been using that were getting cumbersome, and make it easier to run experiments.
I haven't looked closely at imports beyond core.
Test Plan: tested manually against regular grist and grist-core, including imports

Summary:
this moves sandbox/grist to core, and adds a requirements.txt
file for reconstructing the content of sandbox/thirdparty.
Test Plan:
existing tests pass.
Tested core functionality manually. Tested docker build manually.
