feat: add resourceProvider methods [DANTE-1405]

[mohamedturki]

Summary

To give our users and ourselves more convenient access to the new entities: resourceProviders, resourceTypes and resources, we should add them to the contentful-management.js JavaScript library. The library currently contains two separate client implementations that need to be updated: the legacy client and the plain client. This PR adds the first entity, resourceProvider, to both clients.

Description

This PR adds new methods to CRUD resourceProviders:

• Legacy client:

1. AppDefinition methods to upsert and get resourceProviders
2. ResourceProvider methods to upsert and delete a given resource provider

• Plain client:

1. ResourceProvider methods to get, upsert and delete a given resource provider

Motivation and Context
