Fix concurrent use of entity.setAttribute()
Previously we were using a vanilla LinkedHashMap for storing attributes
(ever since the FEATURE_USE_BROOKLYN_LIVE_OBJECTS_DATAGRID_STORAGE
was disabled by default!)
Now uses synchronized set / synchronized map (rather than `ConcurrentMap`,
as need to accept null values), with underlying `LinkedHashSet` to preserve
order.
Adds `EntityConcurrencyTest` for concurrently:
- setting attributes (previously failed fairly often)
- setting config
- adding tags
- adding groups (previously failed sometimes)
- adding children
- adding locations
- adding policies
- adding enrichers
- adding feeds

Fix concurrent use of entity.setAttribute()
Previously we were using a vanilla LinkedHashMap for storing attributes
(ever since the FEATURE_USE_BROOKLYN_LIVE_OBJECTS_DATAGRID_STORAGE
was disabled by default!)
Now uses ConcurrentMap, or for some other things a synchronised set
so that we preserve order with the underlying LinkedHashSet.
Adds EntityConcurrencyTest for concurrently:
- setting attributes
- setting config
- adding tags
- adding groups
- adding children
- adding locations
- adding policies
- adding enrichers
- adding feeds
