Pull request overview

This PR expands the library’s Docker container lifecycle support by introducing a dedicated Flyway container API and adding managed-resource cleanup (container removal + labeled network pruning), along with documentation and test updates.

Changes:

• Added FlywayDockerContainer / FlywayContainer for configuring and running Flyway commands against a MySQL source.
• Introduced managed-resource cleanup via ContainerStarted::remove() and ContainerStarted::stopOnShutdown(), plus labeled network creation and pruning.
• Updated unit/integration tests, README, and Makefile to reflect parallel image pulls, Flyway usage, and managed network labeling.
