merge: Improve web interface (#100)

This pull request addresses several issues with the current web interface.

## Implementation Notes :hammer_and_pick:

* Update dependencies of web UI where possible
* Fix deletion of topology
* Fix duplication of topology
* Only display selected metrics
* Use correct color for login button
* Fix z-index of context selector
* Move project selector into masthead
* Reduce height of application header
* Redesign projects page
* Use PatternFly Charts for plots
* Do not fail on stale Redux state
* Fix overflow of topology sidebar
* Fix deletion of portfolios
* Migrate to composable table

## External Dependencies :four_leaf_clover:

* `classnames` has been replaced by `clsx`
* PatternFly Charts have replaced the use of `recharts`
