By extending TestSuite class with Periodicity mixin it is possible to
enable and configure periodicity.

TestSuite.isRestartAllowed used by
ERP5ProjectUnitTestDistributor.createTestResult in order to create new
Test Result for configured periodicity if finished one already exists.

 - [x] remove method isRestartAllowed
 - [x] use method getAlarmDate
 - [x] in ERP5ProjectUnitTestDistributor.py, I would use "alarm_date = test_suite.getAlarmDate()" and then "if alarm_date and alarm_date <= now: ..."
 - [x] set next alarm date

This make softkeyboard to always popup on mobile, which reduce a lot the page visibility.

This merge request is trying to provide an API so that we can construct urls in a more organised manner than manipulating strings.

The motivation, started from this merge request: nexedi/erp5!333, where absolute_url is overriden for Web Section and Web Site. Then we found that we have to do many dirty changes like:
```
              absolute_url python: here.absolute_url();
              absolute_url python: absolute_url[:-1] if absolute_url.endswith('/') else absolute_url;
```
(more of those in nexedi/erp5@f601d7a5).

So we said we should make an API to have an organised manner, like we have e.g. Base_redirect to handle redirects.

- First commit adds this as a script in erp5_core, along with a test.
- Second commit uses it. It is not on my scope to change all erp5 code, but I focused on changing on the things I already had to in
nexedi/erp5@f601d7a5

@romain , @kazuhiko please make comments. Tests passed, but not on the final revision (did some amendments) and I think better not to re-run suite  before getting comments. Also, @tatuya , I think you are responsible for ERP5 interfaces, so I would like your opinion if erp5_core is the good place, or maybe some other BT or product.

My plan would be to merge this and then nexedi/erp5!333 rebased on this. But in any-way this should be separate from nexedi/erp5!333.

fix attachment parallel synchronization issue

inotifyx is has no support for Python 3 and
it does not seem to be maintained anymore.

The erp5 site creation fails due to a dependency error. Dependency to erp5_full_text_myisam_catalog was added to the erp5_scalability_test business template.

fast synchro is not ready.

Note:
This is not a complete work, i.e. it is not supposed to update all url
calculations of generic ERP5. It is done so that:
- Other pending work can use it
- Demonstrate how the API should be used and test it

for a base document, given the form_id, document_reference and GET parameters

Commit contains also a test in testERP5Type

Allow to overwrite this inside project to init Properties like reference.
