RFR: 8274471: Verification of OCSP Response signed with RSASSA-PSS fails [v2]

[Weijun Wang]

> Extra parameters need to be set for RSASSA-PSS signatures. We already have a helper method for that.
> 
> Some other cleanups:
> 1. When using GET for OCSP, make sure no double slash.
> 2. Several throws clauses are not necessary.
> 
> No regression test. OCSP needs to access an external server.
