ParamStore list_values(key) to get values of key across all commits

[urig]

This PR implements the list_values(key) ParamStore method in InProcessParamStore.

Given a specific key, the method returns a list of its previous (and current) values across commits in the store.

The values are returned as a pandas DataFrame with these columns:

• the value of the key
• time of commit
• commit_id
• optionally, the label assigned to commit

The list is sorted by the time of commit in ascending order.
