Description of problem:
The timeout for loading a dynamic plugin is hardcoded 10 seconds. If the plugin does not load in this time, the UI receives an incomplete JS and fails on syntax error.

Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1. have a dynamic plugin which loads longer than 10 seconds
2. load the UI

Actual results:
1: The UI fails on a syntax error
2: There is no way to configure a longer timeout - e.g. no command line option while starting the bridge process to workaround the issue
3: The 10s timeout feels like a bit too small for larger production setups

Expected results:
1: The UI will log an error saying that the plugin failed to load due to a timeout
2: There is a command line option to run the bridge with a longer timeout
3: The default timeout is much longer than 10s. 

Additional info:
The timeout is in pkg/server/server.go
