lua: implement stub for etcd source

To enable etcd source support in builtin conf module, set the following
CMake variables:

- ENABLE_CONF_SOURCE_ETCD: ON
- ENABLE_ETCD_CLIENT: ON
- CONF_SOURCE_ETCD_LUA_SOURCE: etcd client Lua source files
- ETCD_CLIENT_DIR: path to a directory with etcd client Lua source files

If ENABLE_CONF_SOURCE_ETCD is unset, then a stub implementation is
built, which spits an error on attempt require "conf.source.etcd".

Closes #XXXX
