Ability to create and use alias for index pattern

[tuckson]

Describe the feature:
Would like to have the ability to add a meaningful displayname for an indexpattern. This name should be shown in the locations where a user can choose an indexpattern for his/her search. Not all users are tech savvy and indexnames often are quite technical. For those whore are not a more human readable name without wildcards and abbreviations can be quite helpful in quickly deciding which index to use.

Describe a specific use case for the feature:
On the discover tab there is this dropdown to choose an index pattern, right below the 'add filter' link. I would like to see different names here, so instead of lnd-clust:idx-ms3-sw-ds,lp-clust:idx-ms3-sw-ds and lnd-clust::idx-ms3-sw-ds , Users could see the names London-and-liverpool-subway-stats and London-subway-stats

Above is just an example, but it would be helpful, especially when using remoteclusters together with localclusters and the dropdown is filled with indices with the same names with slight differences.

I can image this is just an alias one could set when creating the index pattern and if it is not set, the indexpattern itselves is shown like it is now.

Another vote for this... most of my index pattern names look something like *:*-logs*,*-logs*. It would be nice if I could make a display name for that of just logs.

Any update on this?

would love to see this! Seems like a quick hit feature for the newly renamed Data Views! 🚀
