Extracted some enhancements from
https://github.com/opencv/cvat/pull/4819

- Extracted common s3 manipulations in tests
- Refactored import/export tests to be more clear

For user-facing functions, keep accepting `str` paths to maintain
compatibility and flexibility, but add support for arbitrary path-like
objects. For internal functions (in `downloading.py` and
`uploading.py`), don't bother and require `pathlib.Path`.

The only code that isn't converted is build-time code (e.g. `setup.py`)
and code that came from openapi-generator.

`isort --version` prints a large banner, which, after shell processing,
is collapsed into one line, and the result is an unreadable mess. Use
`--version-number` instead, which prints just the number.

- OPA tests are now autogenerated
- Updated invocation docs

User authorization documentation updated:

- Screenshots
- Procedure descriptions
- Links

`pathlib` improves code readability and type safety. It is already used
in some of the tests; convert all remaining `os.path` usage to `pathlib`
equivalents.

Fix https://github.com/opencv/cvat/issues/4378

Fixes #4996
- Added job access checks for model launches in the interactive mode

Fixes #4365

The cause of the warning is explained here:

https://devblogs.microsoft.com/typescript/announcing-typescript-3-8-beta/#type-only-imports-exports

Add a webpack configuration option to treat such warnings as errors, to
prevent any more of them from appearing in the future.

Fixes #5215

It's not really clear how the error can be obtained, but this PR adds a
workaround for the problem. There are 2 possible ways to get the
`message` parameter - from an error and from the operation status.

- Our status messages are always represented by a string, no any other
values is assigned.

- rq is trickier here - it receives rq data and [decodes
it](https://github.com/rq/rq/blob/master/rq/job.py#L603-L609) if there
is an error, but the operations can leave None as the `exc_info` value.
Maybe [this issue](https://github.com/rq/rq/issues/1633) is relevant
here.

### Motivation and context
Related #3438 

- When dblclick one of sideviews during drawing - UI is broken
- When mouseleave sideviews during drawing - bbox disappears, need to
draw again
- Sometimes multiple draw boxes exist on view

Example:

Fixed REST API tests after merging #5408 and #5396 to develop
Co-authored-by: NBoris Sekachev <sekachev.bs@gmail.com>
Co-authored-by: NNikita Manovich <nikita@cvat.ai>

Fix https://github.com/opencv/cvat/issues/5245

The PR contains a simple fix. Just return BAD REQUEST if somebody tries
to export a task without data. It doesn't make sense. But a more complex
fix will require changing a massive amount of code. It doesn't make any
sense to support such a weird scenario.

Follow up for #5394

The existing text wont work in a clean repo. This PR adds missing info.

Fix https://github.com/opencv/cvat/issues/5214

1. Stable names for containers (_ vs -)
2. Improve documentation

* rq 1.5.1 uses `collections.Iterable` (long deprecated and deleted in
Python 3.10). 1.5.2 fixes this issue. To avoid potential regressions,
don't bump the version further.

* av 8.0.2 was built with old Cython, which generates C code
incompatible with Python 3.10. The newest version is av 10.0.0, but that
drops support for FFmpeg<4.3, which would make it unbuildable using the
default Ubuntu 20.04 FFmpeg packages. To avoid that problem, use the
previous version, 9.2.0.

Currently, all properties of the server proxy object are created using
`Object.defineProperties` in the constructor, which means that IDEs like
VS Code can't analyze the file's static structure to determine what
properties there are and what types they have. Consequently, things like
autocomplete and go-to-definition don't work.

Fix that by removing the `ServerProxy` class altogether and exporting an
anonymous object with all properties defined statically.
