Update our Oomph setup to use m2e 1.14.0 from their milestone
update site. Unfortunately we need to use the milestone since
the fix for https://bugs.eclipse.org/bugs/show_bug.cgi?id=548652
has not yet made it into a stable m2e release.

Closes gh-19280

Change the Oomph setup to no longer hide nested Maven projects
so that https://bugs.eclipse.org/bugs/show_bug.cgi?id=553789
doesn't get triggered.

  Fix Liquibase endpoint's output with multiple datasources

Fixes gh-19171

See gh-19171

Previously, the endpoint used the same change log history service for
for each SpringLiquibase bean that it processed. This resulted in
pollution of the reported changes as the history of each bean was not
isolated.

This commit updates the endpoint to use a new history service for each
SpringLiquibase bean that is processed.

In general we do not recommend using @PropertySource due to them being
added to the environment too late for auto-configuration to use them. This
commit updates the documentation to mention them in the list of external
sources along with a note.
