New issue 1845: Inconsistent Historical Keys Response Description
https://bitbucket.org/openid/connect/issues/1845/inconsistent-historical-keys-response

Michael Jones:

In [https://openid.net/specs/openid-connect-federation-1\_0-27.html#name-federation-historical-keys-re](https://openid.net/specs/openid-connect-federation-1_0-27.html#name-federation-historical-keys-re) , we updated the example to use `keys` but the normative text still says to use `jwks`.  I believe we should change this use of `jwks` to `keys` and update the description to say that the value is an array of JWKs, as specified in the JWK Set definition in Section 5 of RFC 7517.
