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.

GRPC return codes have changed after switching the Trillian GRPC calls
due to recent changes; therefore we need to adapt for InvalidArgument
which should be returned as a 404 Not Found error to callers.

* Improve code sharing in pluggable type support

This patch removes some of the duplicate logic from specific type implementations and moves it into the base design which hopefully makes writing pluggable types a bit easier.

* 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.

* Remove gzip processing flow completely from rekor

Issue #208 reported different handling of gzipped content via fetch vs
direct upload to rekor server. The code should be consistent, regardless
of whether content was compressed or not - by always attempting to
verify the signature against the (unmodified) byte stream.

This patch removes the gzip decoding completely from rekor and verifies
the bytes supplied or referenced.

Also fixes issue in E2E tests where sending SIGKILL to watch process
caused message to be printed to stderr, which fails the test when
running on MacOS.

them to GCS.

We don't always have a new one, and under load there might be "batches" of entries
all integrated into the same STH. This means there is no guaranteed frequency of updates
or even a guarantee that every index will exist.

The values (and timestamps) should be monotonically increasing though.

Since the API key can be specified as an environment variable and could
be thought of as an authentication credential, it should not be included
in the path to the created entry in the log.

Previously we simply appended the new entry's UUID to the full URL,
which was incorrect if an API key was specified as a query parameter.

In our CI environment there is an artifical delay in between starting
the Rekor services via docker-compose and when the E2E tests are
actually executed due to Go modules being downloaded. In a local
development environment, the download may not be required so the tests
can start before the docker-compose services are actually running.

This introduces a healthcheck for services (where possible), and blocks
the start of the e2e tests until the services are reporting as healthy.
It also forces the use of an empty homedir and rekor config file to
ensure no collision between the tests and the developer's environment.

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.
