Cache parsed RSA key objects in UaaVerificationKeys#5272

Previously, `format_keys` stored raw PEM strings. On every request, `CF::UAA::TokenCoder.new(pkey: pem_string)` re-parsed the RSA key via `OpenSSL::PKey::RSA#initialize`, consuming ~25% CPU under load. Parse the RSA key once when keys are fetched from UAA (every 30s) and cache the `OpenSSL::PKey::RSA` object directly.
