Add support for using multiple signature algorithms

[cicnavi]

Add support for defining and using multiple signature algorithms and keys for protocol (Connect), Federation and VCI purposes.
This is a breaking change since the whole configuration regarding defining signature algorithm and keys is changed to enable defining multiple values.

This also moves the whole JWS, JWK, JWKS handling logic to the SSP OpenID library.
