* Fixes upstream deprecations for containerd * Fixes deprecations in ioutil package usage * Break out separate files for function handlers * Upgrades containerd to 1.7.22 * Fixes default namespace functionality * Pre-deploy checks as per license agreement * Removes extra log messages for payload in HTTP handlers, you can enable FAAS_DEBUG=1 in the CLI instead to see this from the client's perspective * Add additional Google DNS server 8.8.4.4 for functions Signed-off-by: Alex Ellis (OpenFaaS Ltd) <alexellis2@gmail.com>
