CCAR: several changes in Container Manager and Resources Manager
1- remove unused members in MachineParameters, keep only members for requests
the members removed are : alias, protocol, username, applipath, mpiImpl, batch
2- remove the enum policy which is replaced by a new member in MachineParameters (policy)
3- add a new member computerList in MachineParameters structure to specify a list of machines
in a request to Container Manager
3- remove no more used parameters (policy, possibleComputers, componentList
in FindOrStartContainer, FindOrStarParallelContainer, StartContainer,
GiveContainer and GetFittingResources. These operations now take only
one argument : a MachineParameters structure.
4- adapt LifeCycle to these changes
