Display sync percentage in 'chia show -s'

[aqk]

Purpose:

No breaking changes

Current Behavior:

    Current Blockchain Status: Syncing 5109645/5496001 (386356 behind).

Displays number of blocks to be synced

New Behavior:

    Current Blockchain Status: Syncing 5109645/5496001 (386356 behind). (15.06% synced)

Displays number of blocks to be synced
AND
percentage of blockchain synced

Testing Notes:

a potential usability issue is that once you reach 100%, chances are that the new peak has moved away from you and you have to go back to syncing, and "restart" the percentage counter at 0%.

When the node considers itself synced, an alternate message is displayed ("Full Node Synced")

I'm talking about the case where you sync for a long enough time that the chain progresses significantly while you sync. Then you'll be at 100% (of the initial peak you targets). But then back to 0% for the next long sync, catching up.

Ah yes - I notice there are three states:

• "Full Node Synced"
• Syncing
• "Full node not synced"

I wonder if the code uses "Full node not synced" when the sync is stale (the case you mention above).

I'll simulate what you're talking about for print_blockchain_state, and change it in another PR if we need to.
