Support for defining the behavior of click events in visualizations

[arikfr]

Currently we support creating Link typed columns in table visualizations. This allows for simple drill down like scenarios, where you create a link to a parameters based dashboard/query from a table row.

Similarly we should support defining the behavior of a Click event in a visualization (first Plotly charts, then the rest):

1. Link: when clicked, open a link.
2. Set parameter: when clicked, set a parameter in the current context (either dashboard or query).

Not sure about the second one though.

Also, it will be nice to support Plotly ability to select an area in a chart to pass a date range.

About point 2, it would be nice to have the ability to drill down in the current dashboard. Also a default value for (global) parameters can be helpful here. For instance for discrete data use a default value of 'all values' and after a click that it gets a specific value.
