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.
Thanks Josh Smeaton, Tim Graham, Simon Charette, Mariusz Felisiak, and

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

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.
This reduces duplication by allowing AutoField, BigAutoField and
SmallAutoField to inherit from IntegerField, BigIntegerField and
SmallIntegerField respectively. Doing so also allows for enabling the
max_length warning check and minimum/maximum value validation for auto
fields, as well as providing a mixin that can be used for other possible
future auto field types such as a theoretical UUIDAutoField.
Made sql.Where resolve lhs of its child nodes. This is necessary to
allow filter lookups against nested subquery expressions to properly
resolve their OuterRefs to Cols.
Thanks Oskar Persson for the simplified test case.
