#33892: Management commands with flags using action="store_false" create possible
inverted boolean flags in call_command

-------------------------------------+-------------------------------------
In any management command which parses a flag using the action
`store_false` it has an unexpected side effect when calling the management
command from the `call_command` function. When `call_command` parses the
arg it won't be taken into account the action and can create weird
inversions of the intent of the boolean.

**example:**

from the command line this will work fine:

{{{
./manage.py flush --no-input
}}}

However if called from the `call_command` with one of the recommended ways
we might expect `no_input=True` to work the same but it doesn't.

{{{
from django.core.management import call_command

call_command("flush", no_input=True)

You have requested a flush of the database.
This will IRREVERSIBLY DESTROY all data currently in the ":memory:"
database,
and return each table to an empty state.
Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel:

call_command("flush", no_input=False) # This will continue with no input
required
}}}

I'm not sure how widespread this is but `flush` is definitely affected

Comment:

You should use `interactive` instead of `no_input`, see
[https://code.djangoproject.com/ticket/33430#comment:3 comment].

Duplicate of #33430.
