func Prepare(cmd *cobra.Command)

Prepare prepares cmd flag set for the invocation of its usage function by hiding flags that we want cobra to parse but we don't want to show to the user. We do this because not all flags associated with the root command are valid for all subcommands but we don't want to move them out of the root command and into subcommands, since that would change how cobra parses the command line.

For example:

dlv --headless debug

must parse successfully even though the headless flag is not applicable to the 'connect' subcommand.

Prepare is a destructive command, cmd can not be reused after it has been called.
