Create a new clients/ subdirectory at the top level, and move cli/ and tui/ into it, as well as nm-online.c (which was previously in test/, which made no sense). cli/ was split into two subdirectories, src/ and completion/. While this does simplify things (given that the completion file and the binary both need to be named "nmcli"), it bloats the source tree, and we can work around it by just renaming the completion file at install time. Then we can combine the two directories into one and just have it all under clients/cli/.
