m/c/metroctl: add skeleton and dependencies

This adds the skeleton for the Metropolis control command line,
metroctl. It currently consists of a single root command doing nothing
and the dependency updates for viper, the library providing command
line parsing and completion support.
Actual functionality will be in subsequent CLs.
