JobScheduler Agent PowerShell Jobs should support profiles

Current Situation
The JobScheduler Universal Agent Powershell interface does not set the $PROFILE variable and does not load any profile.

Desired Behaviour

• $PROFILE.AllUsersAllHosts, $PROFILE.AllUsersCurrentHost
  • <agent_data>\config\powershell\JobScheduler.PowerShell_profile.ps1
• $PROFILE.CurrentUserAllHosts, $PROFILE.CurrentUserCurrentHost
  • Agent/Job runs as system account: the same profile as stated above is processed
    • <agent_data>\config\powershell\JobScheduler.PowerShell_profile.ps1
  • Agent/Job runs as user account: the profile is looked up in the Users sub-directory for the current user (indicated by <user_name>).
    • <agent_data>\config\Users\<user_name>\powershell\JobScheduler.PowerShell_profile.ps1
