[rrd4j] Use RrdDbPool to prevent ClosedByInterruptException (#13332)
Using the pool prevents exceptions like: ``` java.nio.channels.ClosedByInterruptException: null at java.nio.channels.spi.AbstractInterruptibleChannel.end(AbstractInterruptibleChannel.java:199) ~[?:?] at sun.nio.ch.FileChannelImpl.endBlocking(FileChannelImpl.java:162) ~[?:?] at sun.nio.ch.FileChannelImpl.size(FileChannelImpl.java:388) ~[?:?] at org.rrd4j.core.RrdNioBackend.<init>(RrdNioBackend.java:94) ~[?:?] at org.rrd4j.core.RrdNioBackendFactory.open(RrdNioBackendFactory.java:163) ~[?:?] at org.rrd4j.core.RrdBackendFactory.getBackend(RrdBackendFactory.java:521) ~[?:?] at org.rrd4j.core.RrdDb.<init>(RrdDb.java:627) ~[?:?] at org.rrd4j.core.RrdDb.of(RrdDb.java:500) ~[?:?] at org.openhab.persistence.rrd4j.internal.RRD4jPersistenceService.getDB(RRD4jPersistenceService.java:323) ~[?:?] at org.openhab.persistence.rrd4j.internal.RRD4jPersistenceService.store(RRD4jPersistenceService.java:141) ~[?:?] at org.openhab.persistence.rrd4j.internal.RRD4jPersistenceService.lambda$0(RRD4jPersistenceService.java:211) ~[?:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) [?:?] at java.util.concurrent.FutureTask.run(FutureTask.java:264) [?:?] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:304) [?:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) [?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) [?:?] at java.lang.Thread.run(Thread.java:829) [?:?] ``` Fixes #13297 Also includes a few code improvements.
