Drew Walters a437caa141 [#56] Add use-context subcommand
Currently, airshipctl users switch their current context by modifying
the airshipctl config file or executing airshipctl config set-context
[NAME]. This change introduces the use-context subcommand, which
replaces the current behavior of using set-context without flags. After
this change, set-context will only be used to modify contexts.
