Further backup and restore improvements

Building off of the revamped backup and restore script introduced in 23.9.1, this release further improves the script in a couple of ways.

23.10.0 adds the --encrypt_with option on all sentry export ... methods, and the corresponding --decrypt_with option on all sentry import ... methods. Unsurprisingly, these methods can be used to encrypt and decrypt JSON backups. The --encrypt_with option takes a path to a file containing a public 2048-bit RSA key. An export encrypted in this manner generates a tarball instead of a JSON file, which can be decrypted when passed to a sentry import ... call with a path to the matching private key supplied to the --decrypt_with option.

In addition to the already supported User, Organization, and Global export scopes, a new scope has been added in this release: Config. This scope is used for exporting all data related to globally configuring and administering a Sentry instance, including global options, relay configurations, and administrator accounts, privileges, and roles.
