Make HikariCP GraalVM native image ready

Please make HikariCP GraalVM native image ready by providing native image configuration like reflect-config-json out of the box. It takes too much time to figure it our on its own.

1. For example, see tmy sample project reflect.json where I had to add:

{ "name" : "software.amazonaws.example.product.dao.PoolEntry", "allDeclaredConstructors" : true, "allPublicConstructors" : true, "allDeclaredMethods" : true, "allPublicMethods" : true, "allDeclaredClasses" : true, "allPublicClasses" : true }, { "name": "java.sql.Statement[]", "allDeclaredConstructors" : true, "allPublicConstructors" : true, "allDeclaredMethods" : true, "allPublicMethods" : true, "allDeclaredClasses" : true, "allPublicClasses" : true }, { "name": "com.zaxxer.hikari.util.ConcurrentBag$IConcurrentBagEntry[]", "allDeclaredConstructors" : true, "allPublicConstructors" : true, "allDeclaredMethods" : true, "allPublicMethods" : true, "allDeclaredClasses" : true, "allPublicClasses" : true }

because; for example,

public FastList(Class<?> clazz) { this.elementData = (T[]) Array.newInstance(clazz, 32); this.clazz = clazz; }

isn't understood by native image and (T[]) Array.newInstance(clazz, 32); leads ro Nullpointer exception, because the class Statement which array will be instatiated in the PoolEntry class

PoolEntry(final Connection connection, final PoolBase pool, final boolean isReadOnly, final boolean isAutoCommit) { .... this.openStatements = new FastList<>(Statement.class, 16); }

isn't loaded at the runtime.
