Support a destination_format option in the date processor to format result with DateTimeFormatter

[graytaylor0]

Is your feature request related to a problem? Please describe.
As a user of the date processor, I am unable to format the result of the conversion of my dates to ISO_8601 format strings. The result of the string is always the entire timestamp String (2023-07-23T15:28:15.081-05:00).

Describe the solution you'd like
An optional parameter in the date processor named destination_format. This format can be https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html similar to the OpenSearch index, and will take the ISO_8601 timestamp String that is generated by the Date processor and format it to the DateTimeFormat specified
