Merge remote-tracking branch 'couchbase/alice' into mad-hatter

Perform a no-op merge "ours" merge of alice into mad-hatter, to keep
history tidy and silence 'unmerged_commits.py' script.

Using --stategy=ours, given all these changes are just backports
already in mad-hatter - i.e. this makes zero actual code changes to
mad-hatter.

* couchbase/alice:
  MB-43055: [BP] Ensure ItemPager available is not left set to false
  MB-43453: mcctl: Use passwd from env or stdin
  MB-40531: [BP] Prefer paging from replicas if possible
