Ingo Franzki 154914ee7a zkey: Allow KMS plugin to import a key of a specific type
KMS plugins that support multiple key types need to know which
key type to produce with the kms_import_key() function. Extend
the plugin API to allow a plugin to provide a kms_import_key2()
function, that accepts the key type as additional parameter.

Existing plugins do not need to be changed, as the old function
kms_import_key() still exists, and is still used when the plugin
does not provide a kms_import_key2() function.
