* Adopt new signing/verification APIs from sigstore

This uses the new APIs introduced in sigstore/sigstore/pkg/signature and

* Convert STH to checkpoint format

This switches away from sending the (now deprecated) Trillian LogRootV1
format over to the checkpoint format documented at
https://github.com/google/trillian-examples/tree/master/formats/log



Fixes: #313

Signed-off-by: Bob Callaway <bob.callaway@gmail.com>

This adds an "Attestation" method to the entry interface. Entries can
return an attestation that they would like to store.

The attestations are currently stored in GCS, but it supports any blob store.
The feature is turned off with a flag, and we can set a max size as well.

This adds support for a new pluggable type that can extract signatures

It is this special manifest file that is then signed, and included in a
file within the archive in PKCS7 format. The PKCS7 file also includes
the X509 certificate that can be used to verify the signed manifest file
inside of the JAR.
