This is just a proof of concept without genericity.

These are just optional dependencies to enhance slap console, which works fine
with the default python interpreter, so they should not be required.

To copy those files we should check first if exists because after generate the
egg those files does not exist anymore and it blocks to install the package

Accessing data is done through a web site, in order to surcharge the low level
erp5 scripts/templates/etc.
Navigation is handle with a HATEOAS API.

Overwise, no way to fetch connection url. at aad211b6

WARNING: Also remove alias support from slapos client.

Accept a software_release_url parameter as related document.

Show *_info in highlight way, this permit user "share" documentation and messages for the users (ie.: Link to documentation or Tutorial)

- Show float with 2 digits after . only
- Don't list reversal Sale Transaction Invoices, this only leads to confusion
- Show Payment State as Cancelled if a Reversal Sale Invoice Transaction is started for the Pending account (it means Payment was cancelled).

- List Invoices in Reverse Order (start date), so it is easy to identify if you have something pending to Pay.

If Sale Invoice Transaction is created for account validation (Causality == Cloud Contract), skip this Consistency Script to check prices against Sale Packing List

This rule is used when a Sale Transaction is generated without packing lists. (ie.: Account Validation Case)

Set Computer/Software Instance owner on the support requests, so owner can take a decision.

Add a new "Cloud Contract" document per user.
If the contract is validated, allow instance allocation.

Automatic contract approval is done if user already paid an invoice.
A validation invoice is automatically created if the user has no invoice.

Remove early optimization.

Just to trigger tests.

  This implementation is not optimal from performance point of view,
  however the fix is more urgent and the current implementation has
  nearly the same performance outcome.

  Optimisation should come later on query less objects per time.
