Previously `shell_commands` was a "catch-all" module that included shell commands for each and every used module that has a shell companion. Instead, the new `shell_cmds` module is now used to provide shell commands as individually selectable submodules, e.g. `cmd_gnrc_icmpv6_echo` now provides the ICMPv6 echo command (a.k.a. ping). To still have a "catch all" module to pull in shell commands of modules already used, `shell_cmds_default` was introduced. `shell_commands` depends now on `shell_cmds_default` for backward compatibility, but has been deprecated. New apps should use `shell_cmds_default` instead. For a handful of shell commands individual selection was already possible. Those modules now depend on the corresponding `cmd_%` module and they have been deprecated.
