[Structured Filters] Add "contains" or "is like" as operator in Add Filter UI

[alexfrancoeur]

I thought I had an issue opened for this already but can't seem to find it. Users would like to add a contains or is like operator in the Add Filter UI. The implementation could be something like SQL where you define the wildcards you'd like to use or we could default to wildcards at the start and end of the value.

As this could potentially be a dangerous query to run, it might be worth considering an advanced setting to enable or disable this operator.
