* 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.

* Add Alpine Package type

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).

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.

* Add sha256 prefix to index keys for artifact hashes

This change adds the `sha256:` prefix to index values that are created to simplify searching the transparency log for artifacts. In case we shift to using a different hashing algorithm in the future, this will provide a way to specify it.

* 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.

This makes the binaries "go installable" by their canonical names.

Signed-off-by: Dan Lorenc <dlorenc@google.com>

Since the verification of a signature will, by definition, include
verifying the content has not been altered, it is unnecessary to require
users of the CLI or REST API to specify the SHA256 hash of the content
when creating a new entry into the log.

Note that the server will still compute the hash and store it in the log
for ease of comparison.
