  Polish "Fix Liquibase endpoint's output with multiple datasources"
  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.

  Polish "Use ssl.enabled flag when RabbitMQ address has no protocol"
  Use ssl.enabled flag when RabbitMQ address has no protocol

Closes gh-19109

There is a direct link between the sslEnabled flag and the default port
that should be used by an address. The checks are currently set in two
places:

* Determine which port should be used
* Determine if SSL should be enabled

This commit polishes the initial proposal so that secureConnection is
only set if a protocol is available.
