Improper use of OperationContext.restartRequired() on 7.1 branch

This actually is a subtask of AS7-6035 for additional changes in the 7.1 branch. In particular for two remaining occurrences of OperationContext.restartRequired() at:

org.jboss.as.logging.handlers.file.HandlerFileChange
org.jboss.as.connector.subsystems.datasources.DataSourceDisable

Here is description of the original jira:

Look or an fix uses of OperationContext.restartRequired() that should be using reloadRequired(). There are very few reasons why a full process restart should be needed for a configuration model change to take effect. Typically a full process restart would only be needed for a domain mode server whose JVM configuration settings have been changed in the host model.
