**Steps to reproduce the problem**
- Define a contract template with one line with variable quantity and formula.
- Use that template in a new contract.
- Variable quantity type and formula are not transferred from template to contract.
This is due to the lack of that fields in the tree view that prevents web client to fetch
and store them.
We solve it adding those fields to the contract line tree view, also providing some
visibility logic for not showing the corresponding fields according the type.
No regression tests is provided, as this is only reproducible with web client, not through
code.
Bug description
---------------
`account.analytic.contract.line` inherits
`account.analytic.invoice.line`
`account.analytic.invoice.line` defines field `analytic_account_id`:
- comodel='account.analytic.account'
`account.analytic.contract.line` redefines field `analytic_account_id`:
- comodel='account.analytic.contract'
On attempt to extend `account.analytic.invoice.line` model adding
field that depends on `analytic_account_id.date_start`
Odoo fails to update, because it adds this field to
`account.analytic.contract.line` through inheritance,
and `account.analytic.contract` model have no this field.
What is done
------------
Change inheritance order:
- `account.analytic.invoice.line` inherits
`account.analytic.contract.line`
- no file renames at this stage (this wil be done in next commit)
If you have contract lines with automatic price and your pricelist
contains different prices per quantity, the price is not changed
when computing quantity.
This PR fixes this.

Variable quantity in contract recurrent invoicing
=================================================
With this module, you will be able to define in recurring contracts some
lines with variable quantity according a provided formula.
Configuration
=============
* Go to Sales > Configuration > Contracts > Formulas (quantity).
* Define any formula based on Python code that stores at some moment a
float/integer value of the quantity to invoice in the variable 'result'.
You can use these variables to compute your formula:
* *env*: Environment variable for getting other models.
* *context*: Current context dictionary.
* *user*: Current user.
* *line*: Contract recurring invoice line that triggers this formula.
* *contract*: Contract whose line belongs to.
* *invoice*: Invoice (header) being created.
Usage
=====
To use this module, you need to:
* Go to Sales -> Contracts and select or create a new contract.
* Check *Generate recurring invoices automatically*.
* Add a new recurring invoicing line.
* Select "Variable quantity" in column "Qty. type".
* Select one of the possible formulas to use (previously created).
Big refactoring for allowing to define recurrency at header level for simplifying
the use of the module for most of the cases where you don't need different
recurrency at line level.
Steps to reproduce the problem:
1. Log in as Mitchell Admin.
2. Create contract CNT-A for company CMP-A, assigned to Marc Demo.
3. Create contract CNT-B for company CMP-B, assigned to Marc Demo.
4. Run cron to create recurring invoices.
Actual results:
- Odoo sends automated assignment emails to Marc Demo, which indicate the name of the company activated for `__system__` user whlie the cron was being executed.
Expected results after this patch:
- Odoo sends automated assignment emails to Marc Demo, which indicate the invoice company.

Done through an extra field + inverse in the existing compute. This way, we have
the flexibility of auto-remove custom value if it matches the computed one + we don't
need extra changes in the rest of the code.
