If something causes the number k8s resources to increase beyond a
certain threshold, garbage collection can fail because the query to
retrieve those resources will time out, resulting in a perpetual cycle
of being unable to garbage collect resources.
In lieu of trying to get *every* object each cycle, we can limit the
number of resources retrieved per GC cycle to some reasonable number.

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

* Basic implementation of PKCE
Signed-off-by: Tadeusz Magura-Witkowski <tadeuszmw@gmail.com>
* @mfmarche on 24 Feb: when code_verifier is set, don't check client_secret
In PKCE flow, no client_secret is used, so the check for a valid client_secret
would always fail.

* PKCE: Check clientSecret when available
In authorization_code flow with PKCE, allow empty client_secret on /auth and /token endpoints. But check the client_secret when it is given.

* Enable PKCE with public: true
dex configuration public on staticClients now enables the following behavior in PKCE:
- Public: false, PKCE will always check client_secret. This means PKCE in it's natural form is disabled.
- Public: true, PKCE is enabled. It will only check client_secret if the client has sent one. But it allows the code flow if the client didn't sent one.

When constructing the host address string, the address is
not wrapped in square brackets. This does not work in IPv6
Kubernetes deployments. This commit adds square brackets
around the address. IPv4 was also tested to ensure it works
with wrapped address.

Third Party Resources (TPR) have been removed from Kubernetes for
roughly 2 years. This commit removes the support dex had for them.
Documentation has been updated to reflect this and to instruct users
on how to migrate from TPR-powered dex environment to a Custom Resource
Defintion (CRD) based one that dex > v2.17 will support
