Support for newer versions of ML Metadata (MLMD)

[sergey-serebryakov]

Hi!
CMF currently depends on ml-metadata version 1.11.0. I remember we discussed incrementing this version, but do not remember why this has not been done. I would like to understand if it is possible to upgrade and what it will take.

The reason I am asking this is the following. While working on developer-friendly graph-like API for MLMD, I am experimenting with MLMD's capability to filter nodes by providing an instance of ListOptions class with filter_query field set. The proto file defines usage examples. I was experimenting with it, and found out that I can't filter contexts by parent/child IDs. After googling a bit, I found that this happens to be a bug on MLMD side and has already been reported in this thread. This is fixed in version 1.14.0. This happens to be the latest version released on Aug 9, 2023.
