31630	Replace DatabaseFeatures.introspected_*_field_type attributes with a single attribute.	Tim Graham	Hasan Ramezani	"The current database features to specify the field that a database introspects are:
* introspected_big_auto_field_type
* introspected_small_auto_field_type
* introspected_boolean_field_type

CockroachDB could also use:
* introspected_integer_field_type (CockroachDB introspects IntegerField as BigIntegerField)
* introspected_char_field_type (CockroachDB introspects CharField as TextField)

Rather than adding those attributes, I think it could be more useful to add `DatabaseFeatures.introspected_field_type` which would be a dictionary mapping each field class to the type it's introspected as."
