Currently the E4Application "only" uses the arguments of the application to dtermine if the model should be cleaned. Would be nice it we could allow the LifeCycle handler to set this in the content.

Current implementation:

// Persisted state
Boolean clearPersistedState = getArgValue(IWorkbench.CLEAR_PERSISTED_STATE, appContext, true).map(Boolean::parseBoolean).orElse(Boolean.FALSE);

To allow the lifeycycle handler to change this, we should check first in the context before consulting the arguments.
