These classes can serve as a base class for user enums, supporting
translatable human-readable names, or names automatically inferred
from the enum member name.
Additional properties make it easy to access the list of names, values
and display labels.

OuterRef right hand sides have to be nested, just like F rhs have to,
during the subquery pushdown split_exclude performs to ensure they are
resolved against the outer query aliases.
Expressions should never be prepared as other Lookup.get_prep_lookup
implementations hint at by returning early on the presence of the
resolve_expression attribute.
The previous solution was only handling lookups against related fields
pointing at AutoFields and would break for foreign keys to other fields.
It was also causing bidirectional coupling between model fields and
expressions which the method level import of OuterRef was a symptom of.
Moving the autocomplete attribute into UsernameField allows this to work
for custom forms making use of UsernameField, removes some duplication
in the code, and keeps consistency with the autocapitalize attribute
that is already defined on UsernameField.
This allows using expressions that have an output_field that is a
BooleanField to be used directly in a queryset filters, or in the
When() clauses of a Case() expression.

The Python docs recommend passing a sequence to subprocess.run() when
possible. Doing so allows for automatic escaping and quoting of
arguments.
https://docs.python.org/3/library/subprocess.html#frequently-used-arguments
> args is required for all calls and should be a string, or a sequence
> of program arguments. Providing a sequence of arguments is generally
> preferred, as it allows the module to take care of any required
> escaping and quoting of arguments (e.g. to permit spaces in file
> names).
Also removed `shell=True` where unnecessary.
Unnamed unique and check columns constraints have the same name as
a column. Ensure uniqueness by using custom names.
Thanks Adnan Umer for the report.
