Support key export from Key Vault

For Key Vault 7.2-preview, we need to add support to export keys. This would be a method like KeyClient.ExportKey that takes the key name, key version (both required), and a body with the KeyExportParameters model found in the link below. This only has a single required property named environment (model property: env), so we should take this as a parameter. This returns a KeyVaultKey (model KeyBundle).

This requires a number of other changes:

• Add optional Exportable boolean property to KeyProperties.
• Add ReleasePolicy property to KeyProperties of type KeyReleasePolicy.
• Add PublicExponent integer property to CreateKeyOptions.
• Add “export” to KeyOperation enum. This will correctly impact the CreateKeyOptions class and the KeyClient.UpdateKey method…
• Add ReleasePolicy property to CreateKeyOptions.
• Add ReleasePolicy property to ImportKeyOptions.

See the service version 7.1 -> 7.2-preview diff 🔒 for details.

This doesn’t need to be tracked, let’s add a new task when key export is ready on the service side.
