Retiring Platform Services team content from DevHub

[ty2k]

This pull request relates to the issue #2757 Remove PS Team's migrated content from DevHub, following up on the changes made in #1766, which added placeholder content for pages that are being retired from DevHub.

The changes in this PR remove references to Platform Services team documents in DevHub, replacing them with the new placeholder content pages from #1766. This is done in a way that preserves the use of each page's current URL, so that URLs indexed by search engines or bookmarked by users will still work, but will point to boilerplate text telling them to look in the Private Cloud site or the Private Cloud Technical Documentation site.

Example: Current production page for "Agile Delivery Process"

Updated "Agile Delivery Process" page

@ty2k When a pull request (PR) is over the 200-400 line range (of change) the ability of the reviewer to effectively detect issues quickly diminishes. Your PR is over the preferred length of 300 lines set for this repo. While this cannot always be avoided, please be mindful of the reviewer's time by organizing your work into smaller, more manageable PRs.

I'm going to try merging this without review as I need the "If you can't find..." text from fb4f663 in the master branch to be able to deploy that (in a new PR). Any changes, I will fix going forward.
