Ask the user whether they want to import a missing key before even doing
a search on the keyserver. This will be useful for getting Web Key
Directory support in place: for a WKD, looking up and importing a key
are a single action, so the current key_search -> QUESTION -> key_import
workflow does not apply.
Since only the ID of the package signing key is available before
key_search, we display the packager variable in addition to the key ID
for user convenience.
