slapos/slap/slap.py slap.initializeConnection: Cache master node's Hateoas URL and do not ask many times. Communication to master node is expensive.

slapos/slap/slap.py: Fix ComputerPartition.setConnectionDict. Declare connection_parameter_hash explicitly, UnboundLocalError may occur.

rename checkPromises to checkPromiseList, and move the method to grid/utils so it can be imported by monitor to check promises.


`raise_on_failure` will be used to check all promises without raise. All promises result will be returned.

`profile` True/False will log promise execution time.
