  Polish "Fix use of deprecated Mongo API"
  Fix use of deprecated Mongo API

Closes gh-14318

We now use com.mongodb.MongoClientSettings to configure the reactive
MongoDB driver. This is a breaking change as
MongoClientSettingsBuilderCustomizer and user-provided
MongoClientSettings beans referenced the package the settings type
from com.mongodb.async.client.

MongoClient.getSettings() is deprecated and still in use within tests
until a replacement is available.

Closes gh-12544

This commit deprecates the few 'enabled' flags that control whether
certain meter binders are registered in the context.

Metrics auto-configuration for the JVM, Logback and System-related
information have been moved to individual auto-configurations so that
they can be excluded rather than using the now deprecated flag.

This harmonizes our policy with regards to disabling behaviour,
especially since other similar auto-configurations do not have such
flag.
