Scenario: read a production order's component move
context: 4M stock move in the database, 25k not done nor cancelled on the current product

Before :

After :

The block 1 is improved by the indexes on stock move (db07e39)

The read request time is roughly divided by 2

The second commit (b03f932) speedup the following query

odoo/addons/stock/models/stock_move.py

Line 2119 in 0e958cc

outs = self.env['stock.move'].search(out_domain, order='reservation_date, priority desc, date, id')

by giving a domain that use the index on state. In the following query plan:
