Reassure users by making progress output show a section number

[smy1es]

When extracting very large tenants some of the sections take a long time to run and it is difficult for the user to tell how far through the process of extraction the run has done so far. This pull request adds section numbers to each of the phases giving a simple progress indication which is reassuring. The pull request also makes some of the output text with "Done doing xxxxx" messages unnecessary, so these have been removed. Additionally, the PR calls out explicitly some sections which did not have output before, as some of them can take quite a while to run.
