* 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).

* Move GetRekorClient into util directory

Since other sigstore projects are using GetRekorClient, this moves it
into the pkg/util directory so that the number of dependencies this
brings with it can be minimized.

* 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 retargets #67 at main instead of openapi branch

simplify upload command to reuse common PKI package across client & server

This also breaks the go module dependency on rekor-server.

This is the first step in code reorganization. This follows the patterns
from kubernetes/kubernetes - each binary gets a directory under cmd/.
The main.go file for each binary lives there.
The commands live under cmd//app.

Implement upload command

Accept flags artifact-url,public-key, signature and validate GPG formatting and verify file signature

This change refactors client.go and file.go into an `app` package.

This will make it more easily consumed by rekor-ctl

Once this change is in, I will push rekor-ctl up and then look to
further refactor use of code already duped in rekor-server
