Allow users to configure DatabaseProductName if needed

[metron2]

Related to #1477

This PR allows users to set a DatabaseProductName in their configuration if they wish. This should be useful to people who have trouble with the jdbc call connection.getMetaData().getDatabaseProductName().

Hi, thanks. On one hand, this is something people will shoot themselves to the foot with. On the other, there is apparently no other way, if you are right and the driver does not return anything useful.

Can you please report it to Oracle, so they fix it?

Can you please change the type from string to an enum, so the API is more obvious.

Thanks again

Hi, thanks a lot, I am currently traveling, I will merge it at the end of the next week

Thank you! We really like Shedlock.

I will try with Oracle but typically they don't fix bugs.

ImmutableEnumChecker: enums should be immutable: 'DatabaseProduct' has field 'productMatcher' of type 'java.util.function.Predicate<java.lang.String>', the declaration of type 'java.util.function.Predicate<java.lang.String>' is not annotated with @com.google.errorprone.annotations.Immutable

I'm not sure why sonatype doesn't recognize the final keyword here and the google library it likes isn't in the project already, so I will just ignore this finding.
