Force the use of secure TLS config
This change updates the TLS config used by all pinniped components.
There are no configuration knobs associated with this change.  Thus
this change tightens our static defaults.

There are four TLS config levels:

1. Secure (TLS 1.3 only)
2. Default (TLS 1.2+ best ciphers that are well supported)
3. Default LDAP (TLS 1.2+ with less good ciphers)
4. Legacy (currently unused, TLS 1.2+ with all non-broken ciphers)

Highlights per component:

1. pinniped CLI
   - uses "secure" config against KAS
   - uses "default" for all other connections
2. concierge
   - uses "secure" config as an aggregated API server
   - uses "default" config as a impersonation proxy API server
   - uses "secure" config against KAS
   - uses "default" config for JWT authenticater (mostly, see code)
   - no changes to webhook authenticater (see code)
3. supervisor
   - uses "default" config as a server
   - uses "secure" config against KAS
   - uses "default" config against OIDC IDPs
   - uses "default LDAP" config against LDAP IDPs

f988879b6e Addressing code review changes
- changed to use custom authenticators.Response rather than the k8s one
  that doesn't include space for a DN
- Added more checking for correct idp type in token handler
- small style changes

19281313dd Basic upstream LDAP/AD refresh
This stores the user DN in the session data upon login and checks that
the entry still exists upon refresh. It doesn't check anything
else about the entry yet.

709c10227f Run the LDAP client's integration tests only on Kind
TestSimultaneousLDAPRequestsOnSingleProvider proved to be unreliable
on AKS due to some kind of kubectl port-forward issue, so only
run the LDAP client's integration tests on Kind. They are testing
the integration between the client code and the OpenLDAP test server,
not testing anything about Kubernetes, so running only on Kind should
give us sufficient test coverage.

Improve our integration test "Eventually" assertions.
This fixes some rare test flakes caused by a data race inherent in the way we use `assert.Eventually()` with extra variables for followup assertions. This function is tricky to use correctly because it runs the passed function in a separate goroutine, and you have no guarantee that any shared variables are in a coherent state when the `assert.Eventually()` call returns. Even if you add manual mutexes, it's tricky to get the semantics right. This has been a recurring pain point and the cause of several test flakes.

This change introduces a new `library.RequireEventually()` that works by internally constructing a per-loop `*require.Assertions` and running everything on a single goroutine (using `wait.PollImmediate()`). This makes it very easy to write eventual assertions.

In LDAP, do not log username until we know the user exists.
This prevents accidentally logging a password if the user enters it into the username field by mistake.

cedbe82bbb Default groupSearch.attributes.groupName to "dn" instead of "cn"
- DNs are more unique than CNs, so it feels like a safer default

d2251d2ea7 Use base64 binary-encoded value as UID for LDAP
This is to allow the use of binary LDAP entry attributes as the UID.
For example, a user might like to configure AD’s objectGUID or maybe
objectSid attributes as the UID attribute.

This negatively impacts the readability of the UID when it did not come
from a binary value, but we're considering this an okay trade-off to
keep things simple for now. In the future, we may offer more
customizable encoding options for binary attributes.

These UIDs are currently only used in the downstream OIDC `sub` claim.
They do not effect the user's identity on the Kubernetes cluster,
which is only based on their mapped username and group memberships from
the upstream identity provider. We are not currently supporting any
special encoding for those username and group name LDAP attributes, so
their values in the LDAP entry must be ASCII or UTF-8 in order for them
to be interpreted correctly.

025b37f839 upstreamldap.New() now supports a StartTLS config option
- This enhances our LDAP client code to make it possible to optionally
  dial an LDAP server without TLS and then use StartTLS to upgrade
  the connection to TLS.
- The controller for LDAPIdentityProviders is not using this option
  yet. That will come in a future commit.

3e1e8880f7 Initial support for upstream LDAP group membership
Reflect the upstream group membership into the Supervisor's
downstream tokens, so they can be added to the user's
identity on the workload clusters.

LDAP group search is configurable on the
LDAPIdentityProvider resource.

51263a0f07 Return unauthenticated instead of error for bad username or password
- Bad usernames and passwords aren't really errors, since they are
  based on end-user input.
- Other kinds of authentication failures are caused by bad configuration
  so still treat those as errors.
- Empty usernames and passwords are already prevented by our endpoint
  handler, but just to be safe make sure they cause errors inside the
  authenticator too.
