[Certbot-dev] Certbot 1.3.0 Release

[Brad Warren]

Certbot 1.3.0 has just been released. The changelog entry for the release is:

## 1.3.0 - 2020-03-03

### Added

* Added certbot.ocsp Certbot's API. The certbot.ocsp module can be used to 
  determine the OCSP status of certificates.
* Don't verify the existing certificate in HTTP01Response.simple_verify, for 
  compatibility with the real-world ACME challenge checks.

### Changed

* Certbot will now renew certificates early if they have been revoked according
  to OCSP.
* Fix acme module warnings when response Content-Type includes params (e.g. charset).
* Fixed issue where webroot plugin would incorrectly raise `Read-only file system` 
  error when creating challenge directories (issue #7165).
