switchover: check for pending archive files on the demotion candidate

Browse Source 
If the current primary (demotion candidate) still has any files to archive,
it will delay the shutdown until all files are archived. If there is a
substantial number of files, and/or the archive command executes slowly,
this will probably lead to an unwelcome delay in the switchover process.
