erp5_mrp: Copy price_currency to Manufacturing Execution and Production Packing List (PSA specific?).

In PSA for ME: Problem Report is created from a ME which then build a Returned
IPL from scratch copying properties from the ME. After this Returned IPL is
root-expanded, Real Time Inventory Accounting Rule is expanded too and requires
price_currency.

As a matter of fact immediateReindexObject doesn't call reindexObject on the object

buidler: Add tmp fix/workaround on movement order

builder: Use periodicity to determinate start date

builder mixin: Take into account supply date range before create movement

builder: Hackish immediate reindex of order to work for parallel build

builder: use dedicated script to evaluate min stock

builder: autoPlan only if possible

builder: Reference of order line is reference of resource line

builder: include order delay and effective date

builder: fixup add missing part for effective date

builder: Tweak and fix supply builder

builder: Fixup supply builder

builder: immediate reindex delivery on creation

builder: use _edit on delivery to only reindex modification

builder: Supply builder work with period

builder: Supply builder improved

builder: use flow unit for min stock calculation

builder:  Supply Builder Fix future inventory for parts not activated yet

builder: Supply builder do not create movement for resources that won't be consumed in the future

SimulationTool: getNextAlertInventoryDate can look for the lowest invetory inferior to the reference quantity

To write a pid file so that logrotate can send us signals. This is
still needed for neo storage for now.

See nexedi/slapos!1395

Loading ZConfig will initialize storage and generally might do things
that will cause messages to be emitted.
One actual problem is with neo storage, which configure root logger
when it's not already configured [1], this was causing all logged
messages to be logged in the console when using neo storage.

It is easy to see contents ordered by id by default in ERP5Site.

Protect data from human error. There are unbelievable mistakes. ERP5
is a place to store important data that must not be deleted easily.

Errors in getObject (typically, unauthorized) were hidden by another
error in finally block, because popRequest can only be called if
pushRequest was executed before.

The roles were missing

Thanks to Vincent Pelletier for his help on this bug fix.
