Old slapgrid version will use the "Hosting Subscription" term during
search.
Add a new Skin Selection to rewrite the search query on the fly.

Add a new web site to not rely on the generic one, as it prevent specific customization

It is needed for now to allow migrating the module

force_install prevents removing content (python script, form fields, ...) when updating a bt5.

liblibgolang from pygolang is used in wendelin and because of a current

This enables calling `slapos node format` from the command line.

The configuration is updated every time `StandaloneSlapOS.format()`
is called so that subsequent calls to `slapos node format` produce
the same output.

In the future, `StandaloneSlapOS.format()` could be adapted to call
`slapos node format` directly.

Running slapformat creates a `.slapos-resource` file in each partition.
Running slapgrid emits a warning if a free partition dir is not empty.

With this commit, slapgrid only emits a warning if a free partition
contains entries other than the slapformat dump file.

Optimize the query execution time.

   It isn't possible to pay on payzen zero amount invoices, so just update payment_mode to skip the payment from the search (to prevent bloat activities by relaunching activities that will never change the state of the object).

   Since an Support Request is updated by moving an Item to a project/organisation, its related Events should have their security updated too.

    This is required mostly to be able to edit parameters on the Hosting Subscription shared by others users.

    This feature, also allow us list "Project Members" in futures, to know it the invitations were used by proper users.
