> Add MetadataDynamicCoder to support encode-decode for new fields in Metatdata

> Key: BEAM-13640
> URL: https://issues.apache.org/jira/browse/BEAM-13640

> Priority: P3
> Time Spent: 1h 50m
> Remaining Estimate: 0h

> This Issue is to solve similar problems to wha I had in
> [BEAM-12883.|https://issues.apache.org/jira/browse/BEAM-12883?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel]
> Currently there are 2 Coders for Metadata: default one:
> org.apache.beam.sdk.io.fs.MetadataCoder and enhanced one
> org.apache.beam.sdk.io.fs.MetadataCoderV2, the last can also decode-encode
> lastModifiedMillis and it is done in a new coder in order to support backward
> compatibility.
> This will be hard to maintain, we will need to create a new coder for any new
> field that will be added to Metadata.
> So, as suggested in this [comment:
> #15510|https://github.com/apache/beam/pull/15510#issuecomment-928390587], we
> need to have some new generic coder : MetadataDynamicCoder.
> MetadataDynamicCoder can decode/encode any new fields added to Metadata by
> sending getter, setter and coder.
