nnictl experiment list --all should show experiment name as well

[ksachdeva]

What would you like to be added:

At present

nnictl experiment list --all

shows all the previous experiments however they are listed by experiment ID.

It would be good to display the experiment name as well

Why is this needed:

Since experiment Id is auto generated it is difficult to remember to which experiment it belongs.

Without this feature, how does current nni work：

I have to go in all the experiments to figure out which is the one that I need to look at.

Components that may involve changes:

Brief description of your proposal if any:

One straightforward approach is to add a column with experiment names. These experiment names do not need to unique. User should be able to combine experiment name & date to figure out which one he/she is interested in.

Other approach is to have another command that lists a table that shows the mapping between experiment names and auto generated Ids.
