Hi there,
We want to store 3 different kinds of metadata/config in Iceberg tables.

1. Additional settings/admin properties for a table (e.g. PrimaryKey info)
I think it is* table.properties* according to here
<https://iceberg.apache.org/spec/#table-metadata-fields> and would like to
confirm.

2. User metadata at table level.
Sometimes user wants to take notes about a table. Is there a field for
this? (map of String is good enough and I don't want to abuse
table.properties also as the doc points out)

3. Snapshot name and additional configs
Seems that* snapshot.summary* is for both of these according to here
<https://iceberg.apache.org/spec/#snapshots>, am I right?

Thank you!
