[FEATURE] Data Store - Add TTL to Data Store UI

**Is your feature request related to a problem? Please describe.**
Recently we added the TTL feature to Data store that allow user to specify TTL when create/update keys.

For example, I've added the TTL to my key in the action below

The added key is there, but the TTL is not included in the UI

**Describe the solution you'd like**
I would like to have the TTL show for the key show on the Data Store UI:
- Add a new Column to the UI: **TTL**.
- The value is the current TTL of the key (if set). For example: `3600 seconds`
- Optionally, we can also show the human-readable time remaining (compared to the current time) such as: `3600 seconds (expires in 5 minutes)`
