    Is there a way we could test this with a simple plugin stub?

> Currently when registering schemas in root schema, if a plugin throws an exception we
fail the query. This causes every query to fail as every query needs a complete schema tree.
Plugins could throw exceptions due to transient errors (storage server is temporarily not
reachable). 
> If a plugin throws an exception during schema registration, log an error, skip the plugin
and continue registering schemas from rest of the plugins. If the user is querying tables
from other plugins, the query should succeed. If the user is querying the tables in skipped
plugin, a table not found exception is thrown.
