Docassemble

Fixed
- Bug in `delete_all` feature of `interview_list()`.

Added
- The `query` option for `interview_list()` and API endpoints like
`/api/interviews`.
- Recipes for setting screen parts and watermarking Markdown-to-PDF
files.
- The `raw_result` keyword parameter for `ocr_file()` and
`ocr_file_in_background()` when used with Google Cloud Vision.
Changed
- SQL tables now use a uniqueness constraint on primary key columns.

raising exceptions.
Fixed
- Problem with the processing of `metadata` in the Markdown-to-PDF
feature.
- Issue with `__getattr__()` causing objects to be created as a result
of testing for their existence.

Added
- The option for using Google Cloud Vision when using `ocr_file()` and
`ocr_file_in_background()`.
Changed
- When `new template markdown behavior: True` is set in the
Configuration (which is now part of the default initial
configuration), `template` variables do not have the `markdown`
filter automatically applied when they are used in a DOCX template
file. It is recommended that you add this to your Configuration,
and then modify your `docx template file` templates that use
`template` variables, adding ` | markdown` if necessary.

- Problem with Let's Encrypt certificates not renewing. (Requires a
system upgrade.)
- The `single_worker.log` file was missing from log rotation.
- Erroneous exceptions could be raised if a `DAObject` attribute name
began with `_`. Attributes can begin with `_` but they cannot begin
with `__`.
- The `DBSSLMODE`, `DBSSLCERT`, `DBSSLKEY`, and `DBSSLROOTCERT`
variables were not affected by `ENVIRONMENT_TAKES_PRECEDENCE`.

Added
- The `default language` specifier in `metadata`.
- Recipe for running reports.
Fixed
