WIP initial tests for compute_delivery_date
add explicit dependency on sale_stock

I need this to be able to use the security_lead field in the company. It
is introduced by sale_stock
more WIP: we have an assertion
fix: write date on the lines
WIP production code for delivery dates
first complete test case passes
rename test file
always add the security days
add a second test case
add wizard and refactor to compute only on MTS

MTO logic is different and TODO. For the moment, we raise if we find a
MTO product
fix: search products from outgoing pickings
lint yaml
reduce logging to debug: it is normal behaviour
add mto logic, with a test
rename mts test cases now we have mto
provide a sample cron (disabled)
