Henry Gessau 1c5bf09a03 Use DB field sizes instead of _MAX_LEN constants
Remove The following _MAX_LEN constants from
neutron/api/v2/attributes.py and use the corresponding DB field size
constants from neutron_lib.db.constants instead.

 NAME_MAX_LEN              -->  NAME_FIELD_SIZE
 TENANT_ID_MAX_LEN         -->  PROJECT_ID_FIELD_SIZE
 DESCRIPTION_MAX_LEN       -->  DESCRIPTION_FIELD_SIZE
 LONG_DESCRIPTION_MAX_LEN  -->  LONG_DESCRIPTION_FIELD_SIZE
 DEVICE_ID_MAX_LEN         -->  DEVICE_ID_FIELD_SIZE
 DEVICE_OWNER_MAX_LEN      -->  DEVICE_NAME_FIELD_SIZE

In alembic migration scripts, the raw numerical value is used.
