[FLINK-5663] Prevent leaking SafetyNetCloseableRegistry through Inherâ¦
This PR prevents the SafetyNetCloseableRegistry from leaking into pooled
threads through InheritableThreadLocal.
As first step, we use ThreadLocal instead of InheritableThreadLocal to hold
the closeable registries.
Additionally, we also create safety nets for the file system at the scope
of the checkpointing thread. We hope that this covers already covers most
cases. Other threads could actually also create safety nets for their scope
right now.
