Title: Add key generation and cache

chef_keygen_cache provides an in-vm cache of key pairs to avoid
in-request latency of on-demand key generation. The cache falls back
to in-line generation if the cache is exhausted, but does the
generation in the calling process so that in-line generation is not
serialized through the server.

RSA key pair generation is achieved by shelling out to openssl and
requires that openssl be present on the PATH.
