Codebase currently uses both v3 and v4 versions of the `go-jose`
dependency. To maintain consistency, we should standardize on using only
the latest v4 version.

- Adds a `jwtutils` package to be shared amongst the various
packages in the codebase that make use of JWTs. It's intended to help us
standardize on one library instead of some implementations using
`go-jose` and others using `golang-jwt`.
The main reason we're converging on `go-jose` is due to its support for
JWEs, `golang-jwt` also has a repo to handle it but it doesn't look
maintained: https://github.com/golang-jwt/jwe
