Description

Use the ipfs provide stat command with the new provide system.

• Once we have the new provide system as optional, ipfs provide stat should display the stats relative to the provide system in use.
• The new provide system will show different data, certainly in a different format.
  • So far, we have the total count of provides (incl. reprovides)
  • We can add more metrics:
    • Provide queue size
    • Number of keys currently reprovided
    • Reprovide queue (late regions) size
    • Avg number of provides per second
    • etc.
• We also want to have a command to give the status of a supplied cid (e.g ipfs provide status <cid>, or ipfs provide stat <cid>.
  • It should be fine to use ipfs provide status <cid> and leave ipfs provide stat for generic stats about the provide system.
