ux/ui suggestion: make categories uppercase

[nonsense]

This PR is making categories uppercase for all binaries. Feel free to close if you don't like this UI/UX suggestion.

I think uppercase help differentiate actual commands and other text on the screen, otherwise I always get confused when I see lotus-miner chain actor (which is not a command, lotus-miner info is) vs lotus chain.

COMMANDS:
   init     Initialize a lotus miner repo
   run      Start a lotus miner process
   stop     Stop a running lotus miner
   config   Output default configuration
   backup   Create node metadata backup
   version  Print version
   help, h  Shows a list of commands or help for one command
   CHAIN:
     actor  manipulate the miner actor
     info   Print miner info
   DEVELOPER:
     auth          Manage RPC permissions
     log           Manage logging
     wait-api      Wait for lotus api to come online
     fetch-params  Fetch proving parameters
   MARKET:
     storage-deals    Manage storage deals and related configuration
     retrieval-deals  Manage retrieval deals and related configuration
     data-transfers   Manage data transfers
   NETWORK:
     net  Manage P2P Network
   RETRIEVAL:
     pieces  interact with the piecestore
   STORAGE:
     sectors  interact with sector store
     proving  View proving information
     storage  manage sector storage
     sealing  interact with sealing pipeline
