Cole Helbling 1df0f8912a Add --skip-cert-check flag to zrepl configcheck to prevent checking cert files
It may be desirable to check that a config is valid without checking for
the existence of certificate files (e.g. when validating a config inside
a sandbox without access to the cert files).

This will be very useful for NixOS so that we can check the config file
at nix-build time (e.g. potentially without proper permissions to read cert
files for a TLS connection).
