Update restcontainers service connections support so that
technology specific `@ServiceConnector` annotations are not longer
required.
A single `@ServiceConnector` annotation can now be used to create
all `ConnectionDetail` beans.
Closes gh-35017
Building upon the auto-configuration support for service connections,
this commit adds support for deriving connection details from a
Testcontainers-managed container. Several service-specific
annotations have been introduced. These annotations can be used on a
container field to indicate that it is a source of the details for
a service connection.
