packages/network-explorer: Filters

[rjwebb]

Provide a way to filter entries in Network Explorer. Currently we only allow the user to filter rows in the $actions table by the action name. The /api/models/:model API lets us filter by any column value, so this is less a question of whether we can implement this and more of a design decision.

Some considerations:

• Do we want to be able to filter by multiple columns at once?
• Do we want to encode the current set of filters in the URL, i.e. so that users can bookmark a particular "view" and share/save it? There is a limit to how large we can make the URL, this depends on the user's browser but is around 2000 characters.
• Do we want to filter by indexed columns or any columns?
• We could also allow users to filter by ranges, e.g. number ranges or date ranges, depending on the type of data being represented

Implemented a simple filtering widget for single values: #423

The simple filtering widget is pretty good, let's add filters to the URL and then close this issue
