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.
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.
See RFC6648 which asks that people stop using `X-` on header names.
Also Matt preferred not mentioning "IDP" in the header name.

Also force the LDAP server pod to restart whenever the LDIF file
changes, so whenever you redeploy the tools deployment with a new test
user password the server will be updated.
- Add some fields to LDAPIdentityProvider that we will need to be able
to search for users during login
- Enhance TestSupervisorLogin to test logging in using an upstream LDAP
identity provider. Part of this new test is skipped for now because
we haven't written the corresponding production code to make it
pass yet.
- Some refactoring and enhancement to env.go and the corresponding env
vars to support the new upstream LDAP provider integration tests.
- Use docker.io/bitnami/openldap for our test LDAP server instead of our
own fork now that they have fixed the bug that we reported.

The goal here was to start on an integration test to get us closer to the red
test that we want so we can start working on LDAP.

We had this code that printed out pod logs when certain tests failed, but it is a bit cumbersome. We're removing it because we added a CI task that exports all pod logs after every CI run, which accomplishes the same thing and provides us a bunch more data.

We were previously issuing both client certs and server certs with
both extended key usages included. Split the Issue*() methods into
separate methods for issuing server certs versus client certs so
they can have different extended key usages tailored for each use
case.
Also took the opportunity to clean up the parameters of the Issue*()
methods and New() methods to more closely match how we prefer to call
them. We were always only passing the common name part of the
pkix.Name to New(), so now the New() method just takes the common name
as a string. When making a server cert, we don't need to set the
deprecated common name field, so remove that param. When making a client
cert, we're always making it in the format expected by the Kube API
server, so just accept the username and group as parameters directly.
All controller unit tests were accidentally using a timeout context
for the informers, instead of a cancel context which stays alive until
each test is completely finished. There is no reason to risk
unpredictable behavior of a timeout being reached during an individual
test, even though with the previous 3 second timeout it could only be
reached on a machine which is running orders of magnitude slower than
usual, since each test usually runs in about 100-300 ms. Unfortunately,
sometimes our CI workers might get that slow.
This sparked a review of other usages of timeout contexts in other
tests, and all of them were increased to a minimum value of 1 minute,
under the rule of thumb that our tests will be more reliable on slow
machines if they "pass fast and fail slow".
This is a bit more clear. We're changing this now because it is a non-backwards-compatible change that we can make now since none of this RFC8693 token exchange stuff has been released yet.
There is also a small typo fix in some flag usages (s/RF8693/RFC8693/)

It would be great to do this for the supervisor's callback endpoint as well, but it's difficult to get at those since the request happens inside the spawned browser.

This reverts commit be4e34d0c0.
Roll back this change that was supposed to make the test more robust. If we
retry multiple token exchanges with the same auth code, of course we are going
to get failures on the second try onwards because the auth code was invalidated
on the first try.

I hope this will make TestSupervisorLogin less flaky. There are some instances
where the front half of the OIDC login flow happens so fast that the JWKS
controller doesn't have time to properly generate an asymmetric key.

- This struct represents the configuration of all timeouts. These
timeouts are all interrelated to declare them all in one place.
This should also make it easier to allow the user to override
our defaults if we would like to implement such a feature in the
future.
