Convert to requested type values retrieved from the repository

Try to convert values resolved from the registry to the requested type.

Currently if a component parameter is specified directly in the URI or using the properties component it is converted to the type required by the component if possible:

e.g.

"seda:s?concurrentConsumers=1"
"seda:s?concurrentConsumers={{threadCount}}"

work OK, the String property is converted to Integer.

However if the parameter is a registry reference no conversion takes place:

e.g

"seda:s?concurrentConsumers=#threadCount" 

fails if the values stored in the registry is a String, the value is not converted to Integer
