This is a sub-task of the partitioned namespace, designed to introduce table properties in namespace rest spec. Partition Namespace will set partition fields through create table, create empty table, register table with extended table properties, which are stored in __manifest partition field columns.

Hi @jackye1995 , could you help review this pr, what do you think?

This is a prerequisite for lance-format/lance#5738. After this we can move on PartitionedNamespace.

Optional table metadata as key-value pairs.

lol I removed this because lance tables have metadata, I guess we will have to add this back.

I think we should describe clearly when to expect metadata, when to expect properties. metadata requires loading the table, i.e. load_detailed_metadata=true, whereas properties record information of the table that is outside the table, typically managed by the namespace, for example owner.
