This fixes compatibility with prodaccess tools built with Go 1.15, which
introduced 'X.509 CommonName deprecation' [1].

In addition to k8s certificates, prodaccess now issues HSPKI
certificates, with DN=$username.sso.hswaw.net. These are installed into
XDG_CONFIG_HOME (or os equiv).
//go/pki will now automatically attempt to load these certificates. This
means you can now run any pki-dependant tool with -hspki_disable, and
with automatic mTLS!

In https://gerrit.hackerspace.pl/c/hscloud/+/70 we accidentally
introduced a split-horizon DNS situation:
- k0.hswaw.net from the Internet resolves to nodes running the k8s API
servers, and as such can serve API server traffic
- k0.hswaw.net from the cluster returned no results
This broke prodvider in two ways:
- it dialed the API servers at k0.hswaw.net
- even after the endpoint was moved to
kubernetes.default.svc.k0.hswaw.net, the apiserver cert didn't cover
that
Thus, not only we had to change the prodvider endpoint but also change
the APIserver certs to cover this new name.
I'm not sure this should be the target fix. I think at some point we
should only start referring to in-cluster services via their full (or
cluster.local) names, but right now k0.hswaw.net is an exception and as
such a split, and we have no way to access the internal services from
the outside just yet.
However, getting prodvider to work is important enough that this fix is
IMO good enough for now.

Prodaccess/Prodvider allow issuing short-lived certificates for all SSO
users to access the kubernetes cluster.
Currently, all users get a personal-$username namespace in which they
have adminitrative rights. Otherwise, they get no access.
In addition, we define a static CRB to allow some admins access to
everything. In the future, this will be more granular.
We also update relevant documentation.
