Process errors + throughput indicator on process view and process list view

[arkadius]

Would be nice to have available more information about how process is performing in Nussknacker.

Currently user need to switch to grafana to see what is throughput on which node or that some node reported errors.

After proposed change user can see throughputs (succes/rejected) on process list and indicator that there are some errors during processing events. After entering to process details view he or she will see exact information about throughput of messages processed by node and error indicator if there are some errors during processing by this node.

Issues that should be considered:

1. How it should behave when structure of process will change (e.g. node added/removed/changed parameters) and changes are not deployed yet?
2. How this feature should be connected with "Counts" feature to keep consistent experience during usage of them?

Further extensions:

1. We can add popover displaying what errors were reported.
2. We can add popover how throughput looked like in the past.
