Wallet no longer needs to print scan height when scanning / unlocking
PROGRAMMING TASK
Description of Task
We added a println to siad to print out the current scan height of the wallet when it is unlocking so that we had some way to see the unlock progress. This progress is now available through the API, so the printlns can be removed and any siac
commands that depend on them can be given a way to track the progress through the API.
Reason or Need for Change
siad should have minimal printlns, it should not be the primary way that applications and users communicate with siad.
Design / Proposal
Remove the printlns, and then go to the major siac commands like siac wallet unlock
and a few of the other commands which trigger rescan and re-work them to query the api for progress and for the siac commands to display the progress.
