The Kube API server code that we use will cast inputs in an attempt
to see if they implement optional interfaces. This change adds a
simple wrapper struct to prevent such casts from causing us any
issues.

This change updates the default NO_PROXY for the supervisor to not
proxy requests to the Kubernetes API and other Kubernetes endpoints
such as Kubernetes services.
It also adds https_proxy and no_proxy settings for the concierge
with the same default.

In the upstream dynamiccertificates package, we rely on two pieces
of code:
1. DynamicServingCertificateController.newTLSContent which calls
- clientCA.CurrentCABundleContent
- servingCert.CurrentCertKeyContent
2. unionCAContent.VerifyOptions which calls
- unionCAContent.CurrentCABundleContent
This results in calls to our tlsServingCertDynamicCertProvider and
impersonationSigningCertProvider. If we Unset these providers, we
subtly break these consumers. At best this results in test slowness
and flakes while we wait for reconcile loops to converge. At worst,
it results in actual errors during runtime. For example, we
previously would Unset the impersonationSigningCertProvider on any
sync loop error (even a transient one caused by a network blip or
a conflict between writes from different replicas of the concierge).
This would cause us to transiently fail to issue new certificates
from the token credential require API. It would also cause us to
transiently fail to authenticate previously issued client certs
(which results in occasional Unauthorized errors in CI).

This change updates the pinniped CLI entrypoint to prevent browser
processes that we spawn from polluting our std out stream.
For example, chrome will print the following message to std out:
Opening in existing browser session.
Which leads to the following incomprehensible error message from
kubectl:
Unable to connect to the server: getting credentials:
decoding stdout: couldn't get version/kind; json parse error:
json: cannot unmarshal string into Go value of type struct
{ APIVersion string "json:\"apiVersion,omitempty\"";
Kind string "json:\"kind,omitempty\"" }
This would only occur on the initial login when we opened the
browser. Since credentials would be cached afterwards, kubectl
would work as expected for future invocations as no browser was
opened.
I could not think of a good way to actually test this change. There
is a clear gap in our integration tests - we never actually launch a
browser in the exact same way a user does - we instead open a chrome
driver at the login URL as a subprocess of the integration test
binary and not the pinniped CLI. Thus even if the chrome driver was
writing to std out, we would not notice any issues.
It is also unclear if there is a good way to prevent future related
bugs since std out is global to the process.

After merging the new Kube 1.22 ExecCredential changes from main into
this feature branch, some of the new units test on this feature branch
needed to be update to account for the new ExecCredential "interactive"
field.
- Add `AllowPasswordGrant` boolean field to OIDCIdentityProvider's spec
- The oidc upstream watcher controller copies the value of
`AllowPasswordGrant` into the configuration of the cached provider
- Add password grant to the UpstreamOIDCIdentityProviderI interface
which is implemented by the cached provider instance for use in the
authorization endpoint
- Enhance the IDP discovery endpoint to return the supported "flows"
for each IDP ("cli_password" and/or "browser_authcode")
- Enhance `pinniped get kubeconfig` to help the user choose the desired
flow for the selected IDP, and to write the flow into the resulting
kubeconfg
- Enhance `pinniped login oidc` to have a flow flag to tell it which
client-side flow it should use for auth (CLI-based or browser-based)
- In the Dex config, allow the resource owner password grant, which Dex
implements to also return ID tokens, for use in integration tests
- Enhance the authorize endpoint to perform password grant when
requested by the incoming headers. This commit does not include unit
tests for the enhancements to the authorize endpoint, which will come
in the next commit
- Extract some shared helpers from the callback endpoint to share the
code with the authorize endpoint
- Add new integration tests
