Enhancement Request : Add 'Title" option to Visualisations

[LeeSyd]

I often find that I would like to specify a different "Title" on a visualisation to the name under which I would want to save it and organise within Kibana. For example, I monitor Application performance for a number of apps and would like to make dashboards available to some users. I would save a visualisation with a name like 'App-AppNameA-LineOfAverageResponse' but on an Application specific Dashboard, would like the title the user sees to be 'Average Response Time'

Is possible, this would also be extended to enable me to specify legend names for each Aggregation, e.g. rather than the default 'Average FieldName' it would be "Response Time" or similar

I'll assume #5607 came from the same organization? Added a few comments there. Dupe of #3393
