adjustments in for preparation for hpcm/ngi providers

[jacobsalmela]

Summary and Scope

• moves all init() functions to main.go by making each package's
  init() public (Init()) so they can be run in a specific order
• uses a new RegisterProviderCommand to add provider versions of each
  comand as a subcommand to cani's command. this currently requires the
  passing of a provider name for all calls but easily allows for each
  provider to define their own settings and not clash with each other
• adds a utils.CloneCommand() funciton to clone a cobra command, which
  providers can use to create and modify the commands as needed
• converts recommendations.Print() method to a provider-specific
  method: root.D.PrintRecommendations(cmd, args, recommendations)
• changes some variable names from bootstrapCmd to caniCmd to better
  distinguish cani vs. provider
• moves additional cray-sauce like cabinet vlans out of the cmd
  package and into the csm package where it belongs
• updates provider.ProviderCommands interface for all
  currently-supported commands
• adjusts test to call csm, which will begin to adjust tests for
  multiple providers
• adjusts help fixtures as needed
• converts some CSM DEBUG statements to TRACE since development will
  be minimal on CSM and less of that info is relevant to multiple
  providers
• changes some cmd.Name() conditionals to cmd.Parent().Name()
  since the provider command is a sub command
• updated makeprovider command for changes (some stupid changes, but
  they meet the immediate need)
