Switch to PHP HubSpot API v3 SDK Client

I have created a branch and MR that uses v4 of hubspot/api-client. I have only worked in the case of using a private app access token and the changes work for me. I do not have a case that uses OAuth and somebody else that does should take it from here.

Prepared ManagerInterface and some actual info to settings form.

We've created a separate module as a solution to this issue:
https://www.drupal.org/project/hubspot_client →
It covers the syncing of HubSpot IDs to Drupal as well.

I'm working on a version for Drupal 10 + PHP 8.1 + latest hubspot-api-php. I need both of OAuth and Private App access token, so i will try to handle both cases and create a Merge Request next week.

Hi

I've created a MR with a full update of the module for OAth and Private App access token.

Compatibility:
- Drupal 10
- latest hubspot/api-client (v10)
- PHP 8.1

Some notes:
- tried to re-use as much code as possible
- re-used the access_key config (deprecated), to save there the new Private App access token (breaking change)
- added new public methods for getting the handler directly with OAuth or Private App access token
- fixed some minor bugs (undefined indexes, color for status was not working)

I think we should add this to a new version, like 3.0 alpha, because of the breaking changes.

VladimirAus → changed the visibility of the branch 3334746-api-v3 to hidden.

Works well and tested on majority of the objects.
