cleanup: release artifact resolver resources more eagerly

Browse Source 
Set resolver executor thread context classloader to null by
default. This allows collection of class realms that triggered
thread creation (one of plugin realms, typically).

Use Disposable#dispose to shutdown resolver executor server,
remove now redundant #finilaze() implementation.
