> NIFI-2583 added the ability (via dynamic properties) to specify initial Max Values for columns, to enable the user to "pick up where they left off" if something happened with a flow, a NiFi instance, etc. where the state was stored but the processing did not complete successfully.
> This feature would also be helpful in GenerateTableFetch, which also supports max-value columns.
> Since NIFI-2881 adds incoming flow file support, it's more useful if Initial max values can be specified via flow file attributes. Because if a table name is dynamically passed via flow file attribute and Expression Language, user won't be able to configure dynamic processor attribute in advance for each possible table.
> Add dynamic properties ('initial.maxvalue.<max_value_column>' same as QueryDatabaseTable) to specify initial max values statically, and also use incoming flow file attributes named 'initial.maxvalue.<max_value_column>' if any.
