New Feature / Enhancement Checklist

• [x] I am not disclosing a vulnerability.
• [x] I am not just asking a question.
• [x] I have searched through existing issues.

Current Limitation

The findAll API isn't available causing people to use "find" without thinking about it and then they have bugs if they don't think about paging :)

Feature / Enhancement Description

Expose the findAll like the JS parse SDK do.

Example Use Case

fetching more than 100 objects :)

Alternatives / Workarounds

everyone builds it for themselves
