PR #815 fixed the Kubernetes storage implementation by correctly
returning storage.ErrAlreadyExists on POST conflicts. This caused a
regression in TPR creation (#822) when some, but not all, of the
resources already existed. E.g. for users upgrading from old
versions of dex.
Fixes#822
The "at_hash" claim, which provides hash verification for the
"access_token," is a required claim for implicit and hybrid flow
requests. Previously we did not include it (against spec). This
PR implements the "at_hash" logic and adds the claim to all
responses.
As a cleanup, it also moves some JOSE signing logic out of the
storage package and into the server package.

Dex's Postgres client currently uses the `timestamp` datatype for
storing times. This lops of timezones with no conversion, causing
times to lose locality information.
We could convert all times to UTC before storing them, but this is
a backward incompatible change for upgrades, since the new version
of dex would still be reading times from the database with no
locality.
Because of this intrinsic issue that current Postgres users don't
save any timezone data, we chose to treat any existing installation
as corrupted and change the datatype used for times to `timestamptz`.
This is a breaking change, but it seems hard to offer an
alternative that's both correct and backward compatible.
Additionally, an internal flag has been added to SQL flavors,
`supportsTimezones`. This allows us to handle SQLite3, which doesn't
support timezones, while still storing timezones in other flavors.
Flavors that don't support timezones are explicitly converted to
UTC.
ghodss/yaml converts from YAML to JSON before attempting to unmarshal.
This allows us to:
* Get the correct behavor when decoding base64'd []byte slices.
* Use *json.RawMessage.
* Not have to support extravagant YAML features.
* Let our structs use `json:` tags
Use a hash algorithm to match client IDs to Kubernetes object names.
Because cryptographic hash algorithms produce sums larger than a
Kubernetes name can fit, a non-cryptographic hash is used instead.
Hash collisions are checked and result in errors.
Using the default KUBECONFIG environment variable to indicate that
the Kubernetes tests should be run lead to cases where developers
accidentally ran the tests. This has now been changed to
"DEX_KUBECONFIG" and documentation hsa been added detailing how to
run these tests.
Additionally, no other storage reads environment variables for its
normal configuration (outside of tests) so the Kubernetes storage
no longer does.
Overall, be less surprising.
These status codes spam the error logs for events like key rotation
and third party resource creation. In these cases "bad" status codes
are expected and shouldn't be automatically printed.
The in cluster kubernetes client currently requires using the
downward API to determine its namespace. However this value can be
determine by inspecting the service account token mounted into the
pod. As a fallback, use this to guess the current namespace.
