[ADD] oca_module_updates

[etobella]

This module allows to monitor status of OCA modules on Pypi.

It will not check created PR, but only the status of the module on Pypi. So, we will detect if a PR has been merged.

Usage

• Access the menu OCA Updates
• Create a new module. You should set the version of the module
• You can refresh the data manually pressing the button Refresh
• Otherwise, you can wait for the cron job to refresh the data

It is important to notice that the cron job just does a 100 modules on each refresh. If you have a lot of modules, you should change the cron job to run more often.
