  Polish "Add generated-snippets as output to test goal"
  Add generated-snippets as output to test goal

Closes gh-22555

See gh-22555

The generated snippets were not declared as an output to the
`spring-boot-actuator-autoconfigure` test goal so when the test was
pulled from the cache, it did not contain the `generated-snippets`
directory. This directory is required as an input to the Asciidoctor
plugin.

  Polish "Disable metrics export in integration tests"
  Disable metrics export in integration tests

Closes gh-21658

See gh-21658

This commit introduces a new property to globally disable metrics
export. In integration tests, this property is automatically set to
disable everything but in-memory metrics.

This commit also introduces a `@AutoConfigureMetrics` annotation that
can be used for integration tests that require metrics export to operate
as they would in an application.

* gh-22550:
  Disable extra scans for full profile.

Closes gh-22550

The extra scans were not disabled for the full profile, only the
regular profile.
