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

b5b8cab717 Refactors:
- pull construction of authenticators.Response into searchAndBindUser
- remove information about the identity provider in the error that gets
  returned to users. Put it in debug instead, where it may show up in
  logs.

  that doesn't include space for a DN
- Added more checking for correct idp type in token handler
- small style changes

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.

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.

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.

7e76b66639 LDAP upstream watcher controller tries using both TLS and StartTLS
- Automatically try to fall back to using StartTLS when using TLS
  doesn't work. Only complain when both don't work.
- Remember (in-memory) which one worked and keeping using that one
  in the future (unless the pod restarts).

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.

fec3d92f26 Add integration test for upstreamldap.Provider
- The unit tests for upstreamldap.Provider need to mock the LDAP server,
  so add an integration test which allows us to get fast feedback for

- Automatically wrap the user search filter in parenthesis if it is not
  already wrapped in parens.
- More special handling for using "dn" as the username or UID attribute
  name.
- Also added some more comments to types_ldapidentityprovider.go.tmpl
