As we have moved away from the rekor.dev domain, switching over to

* Add Log ID to LogEntry field

Since the signed entry timestamp (SET) will be able to prove insertion into the log, adding the log ID (aka public key SHA256 hash) makes it easier to know which log the entry came from.

* 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 is changing as part of the general trillian signature changes.
The trust model is still client -> database, our server trusts our
database so we can pass signed messages on directly to users without
double verification.

This patch removes the /api/v1/log/entries/{uuid}/proof endpoint. If you
have the UUID (aka the leaf Merkle hash), you likely want proof that the
content represented by that hash is included in the log. There's no need
for a separate /proof endpoint to deliver the same content.

This commit also ensures that the getLogEntryByIndex and
getLogEntryByUUID endpoints return an inclusion proof as part of their
response content. The search endpoint also now returns the inclusion
proof of all entries returned from the query.

With this patch, Rekor no longer uses the deprecated `GetLeavesByHash`
Trillian API.

We don't always have a new one, and under load there might be "batches" of entries

The loginfo API returns both the current size, root hash, as well as the
signed tree head that callers can verify if they wish. The CLI does a
check to verify the signature on the tree head returned, but was
reporting the unsigned size and hash. This change ensures that the
values match and prints the values from the signed tree head.

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.

By using viper.GetString(flag), viper will return the values of that
argument from a precedence order (including CLI arguments). However, if
a value was passed in through an environment variable or as a value in
the config file, it would skip the validation step since that logic was
defined against the FlagSet for command line arguments.

This change causes validation to be done across all input methods.
