There's been some discussion in #1065 regarding what to do about
refreshing groups. As it stands today dex doesn't update any of the
claims on refresh (groups would just be another one). The main concern
with enabling it is that group claims may change more frequently. While
we continue to wait on the upstream refresh flows, this adds an option
to enable the group claim. This is disabled by default (so no behavioral
change) but enables those that are willing to have the delay in group
claim change to use oidc IDPs.
Workaround to #1065
The default cipher suites used by Go include a number of ciphers that
have known weaknesses. In addition to leaving users open to these
weaknesses, the inclusion of these weaker ciphers causes problems with
various automated scanning tools.
This PR disables the CBC-mode, RC4, and 3DES ciphers included in the
Go standard library by passing an explicit cipher suite list.
The ciphers included here are more line with those recommended by
Mozilla for "Intermediate" compatibility. [0]
*Performance Implications*
The Go standard library does capability-based cipher ordering,
preferring AES ciphers if the underlying hardware has AES specific
instructions. [1] Since all of the relevant code is internal modules,
to do the same thing ourselves would require duplicating that
code. Here, I've placed AES based ciphers first.
*Compatibility Implications*
This does reduce the number of clients who will be able to communicate
with dex.

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
