Add autoincrement=false to some columns (DM-43097)

Columns which are primary keys by default have autioncrement=auto
in sqlalchemy which for single-column PK enables autoincrement.
This does no big harm for APDB schema but creates unnecessary
sequences in postgres. To avoid those extra sequences I mark all
integer PK columns as autoincrement=false.
