In order to restrict some uom field to some uom category, it is required to
add a measurement type on uom.category. Also, this will lessen the use of
master data.
Some technical justifications:
- measure_type is not required, to allow people creating their own
uom.category. Those ones will not interfere with addons business.
- measure_type is unique: we restrict to only one category containing
time, weight, ... in order to avoid mismatch category during conversion.
(2 different weight categories can not be converted).
- measure_type on uom.uom is stored: to allow search and domain on
field, we need to store it. Usually, UoM are not updated every day,
and the number of uom in a database is not that important.
To illustrate this mecanism, a domain is added on
'project_time_mode_id', in project module. This field
is use as timesheet default uom, and we obviously want to
restrict it to time category (timesheeting in liter does
not make sense ...)
Task #1820076
Moves UoM models, test and data to a new addon in
order to be able to use uom without product.
A simple example is be to be able to use UoM for
timesheets.
This commit only move code, and adapt xml ids
without chaging any feature or functionnal
behavior.
Note: 'product' module now depends on new
'uom' module.
