[Certbot-dev] Certbot 1.10.0 Release

[Brad Warren]

We just released Certbot 1.10.0. The changelog for the release is:

## 1.10.0 - 2020-12-01

### Added

* Added timeout to DNS query function calls for dns-rfc2136 plugin.
* Confirmation when deleting certificates
* CLI flag `--key-type` has been added to specify 'rsa' or 'ecdsa' (default 'rsa').
* CLI flag `--elliptic-curve` has been added which takes an NIST/SECG elliptic curve. Any of
  `secp256r1`, `secp284r1` and `secp521r1` are accepted values.
* The command `certbot certficates` lists the which type of the private key that was used
  for the private key.
* Support for Python 3.9 was added to Certbot and all of its components.

### Changed

* certbot-auto was deprecated on Debian based systems.
* CLI flag `--manual-public-ip-logging-ok` is now a no-op, generates a
  deprecation warning, and will be removed in a future release.

### Fixed

* Fixed a Unicode-related crash in the nginx plugin when running under Python 2.
