[SaaS Connector] Salesforce (access)

[galvana]

Purpose

Adds Salesforce connector with access functionality

Changes

The Salesforce APIs cover a broad scope of functionality so for this first pass we will only be covering the following collections

• Contacts
• Cases
• Leads
• Campaign Members
• Accounts

We have added these files:

• Config file salesforce_config.yml for configuration
• Dataset file salesforce_data.yml
• Test cases file test_salesesforce_task.py and salesforce_fixtures.py for testing
• Utility test file saas_tets_utility.py

We have updated these files:

• saas_config.toml to contain Salesforce data
• conftest.py to add Salesforce test

Checklist

• Update CHANGELOG.md file
  • Merge in main so the most recent CHANGELOG.md file is being appended to
  • Add description within the Unreleased section in an appropriate category. Add a new category from the list at the top of the file if the needed one isn't already there.
  • Add a link to this PR at the end of the description with the PR number as the text. example: #1
• Good unit test/integration test coverage

Ticket

Fixes #398

just need a very minor change to fixture method name that was copy and pasted - the method isn't being used yet but let's clean it up now anyway.

also, i think it's fine to include the poll_for_existence refactor on this PR even though it's not being explicitly used, but may be good to make the core fidesops team aware just as an FYI. i also assume we've tested (or CI has covered) that the refactor hasn't broken anything in existing saas integration tests.

looks like we forgot to change the method name from stripe to salesforce -- that was probably in my initial work, whoops :)

looks good!
