Lookups of specific keys are too slow

[nomis]

The OpenDNSSEC ods-hsmutil list command is extremely slow.

First it does a lookup of all private keys using C_FindObjects* which takes 2-3 seconds because there are over 300 of them.

Then it does a lookup of the public key corresponding to each private key using C_FindObjects* which takes 2-3 seconds per key because it goes through all of the keys again.

There doesn't appear to be a better PKCS#11 API for doing this so HSMs must be expected to have faster lookup processes, at least when a specific key ID is provided.

The list command can be improved but key access shouldn't take 2+ seconds.

For normal key access it will take 4-5 seconds because it does a lookup by ID for the private key and then for the public key.
