Describe the bug

I'm unable to modify 'Page size' parameter for an existing SCIM provider.
At developer tools I see PUT request which doesn't contain the changed field. It's definitely a UI bug.
Besides that, Creation form doesn't work properly with this field as well. POST request doesn't contain field sync_page_size even when it contains non-default value.

How to reproduce

Create provider:

1. Create a new SCIM provider with non-default value at 'Page size' field
2. Open edit page for the just created provider and check the 'Page size' field. It has the default value.

Edit provider:

1. Open Edit page for a SCIM provider
2. Modify 'Page size' field and save
3. Open Edit page for the just modified SCIM provider and check 'Page size' field. The changes are not applied.
4. Check the provider configuration at the PG database. Changes are not saved at the DB.

Expected behavior

When I modify value for 'Page size' parameter for a SCIM provider and press 'Save':

• it has to be sent at the corresponding API request
• it has to be saved at the DB
• it has to be displayed on the provider parameters page (after refresh)
