[FEATURE] improve CLI command name and parameters with consistent naming

[cnlangzi]

for now, there are some naming rules on cli command name

• lower-case: list-all, add-collab
• lowercase: listallocations, addcurator,encryptionpublickey
• prefix: alloc-cancel,alloc-fini
• without prefix: get
• fullname: list-all
• shortname: ls-blobbers

And there are some naming rules on cli command parameters

• lower-case : rx_pay,free_storage,read_price, write_price
• lowercase: remotepath
• fullname: allocation
• shorname: collabid,mcct

It is better to rename all of them with consistent naming rule.

eg lower-case with prefix and short name, only root file system commands should be named without prefix.

for examples:

• mkdir, copy, upload, download,delete...etc
• alloc-new, alloc-get, alloc-update
