Without this we can't properly re-run IndexKeys() on the log data because old minisign
keys were stripped to no longer contain the KeyID or Algorithm field.

Signed-off-by: Dan Lorenc <lorenc.d@gmail.com>

We were previously stripping off the keyid/algorithm identifiers in minisign public keys.
These should be included in here to properly canonicalize/reconstruct the keys for verification.

The CryptoPubKey function only returned the key value, but we should
retrieve it from the cert if set. This fixes the rest of #918.

This commit adds a PATH lookup to the openSSH tests.
This prevents failing tests on systems with no ssh-keygen
in PATH.

Previously we returned an HTTP 500 "error canonicalizing entry" error if
Rekor was unable to parse or verify the proposed content of a new log
entry. This adds a new error type ValidationError that allows
implementers of the Canonicalize method to delineate between internal,
transient errors and errors that clients can rectify.

With this patch, errors parsing or validating (provided or referenced)
artifacts will return an HTTP 400 message to the client with a message
about the issue.

Fixes: #362

* Refactor PKI factory and add type checking

This allows for more DRY addition of new PKI types, and stricter
type checking. This also allows for simpler enumeration of
supported PKI formats which will be used in further updates to
simplify the CLI codebase.

This adds support for the alpine package format used by Alpine Linux,
which is the concatenation of three tgz files (signature, control data,
and then the actual package files).

* Adopt new signing/verification APIs from sigstore

This uses the new APIs introduced in sigstore/sigstore/pkg/signature and
removes most of the calls directly to the golang crypto APIs.

* Add new type for JAR archives

This adds support for a new pluggable type that can extract signatures
from signed JAR files. Per the JAR spec, a special manifest file is
created with the digest hashes of all included content in the JAR file.
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.

The error was turning signature bytes into a string directly. We could
base64 encode it, but that's not terribly useful either.
