Expose method to refresh Api Resources

[nimajalali]

When adding or editing custom objects in Salesforce the api resources become invalid and need to be refreshed.

Today you have to restart the process to initiate a refresh.

The following resources should be refreshed when this method is called:

apiResources apiSObjects apiSObjectDescriptions apiMaxBatchSize

Thread safety needs to be implemented as the resources that need updating are map objects.
