What do you think about change SoftwareReporter -> ChromeCleaner for the cases
where it is the cleaner and not the reporter?

Like SoftwareReporterCleanerDownloadStatus -> ChromeCleanerDownloadStatus

Or Maybe still prefix it with SoftwareReporter to group with the others

As discussed, we have several histograms prefixed with SoftwareReporter.Cleaner.
Even though it's not ideal, we can't get rid of all legacy analysis, so I'll
keep naming consistent.

Where is recently prompted used and how it is different from already prompted?

Good catch! Removed.
