*: developer machine HSPKI credentials

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!
