Description
Original issue #1027, Add bulk1 functions in salesforce adaptor

bulk1.query()
bulk1.insert()
bulk1.update()
bulk1.upsert()
bulk1.destroy()

[mtuchi]

insert and update are getting stuck, making the job execution really slow. I need more time to investigate this

This is done, we should QA the new changes, I have opened a ticket here #1361
