Added new pre-defined usergroup called hostconsole

The new pre-defined usergroup named "hostconsole" is added to
differentiate access between host console and manager console.
The only users allowed to interact with host console are part of the
"hostconsole" group and they are in an administrator role.

Note: The changes are spread across multiple repositories listed under
"Related commits:"

The bmcweb changes to incorporate new group are as follows:
- The new user is added in the hostconsole group only if it has an
  administrative role.
- The ssh usergroup is only translated to ManagerConsole redfish group
  and hostconsole usergroup is translated to HostConsole redfish group.
- The following changes are made to check the privileges for host console
  access
    - The new OEM privilege "OpenBMCHostConsole" added for host console
      access. This privilege is not shared externally hence it is not
      documented.
    - Updated obmc_console BMCWEB_ROUTE to use the new privilege.
    - Router functions now save user role and user groups in the session
    - getUserPrivileges() function now takes session reference instead
      of user role. This function now also checks for the user group
      "hostconsole" and add the new privilege if user is member of this
      group.
    - Updated all callers of the getUserPrivileges to pass session
      reference.
    - Added test to validate that new privilege is set correctly.

Tested:
  Loaded code on the system and validated that;
  - New user gets added in hostconsole group. NOTE: Prior to this commit
    all groups are assigned to new user. This drop does not change that
    behavior.
  - Access from the web gui is only available for users in hostconsole
    group. Used IBM internal simulator called simics to test this. This
    simulator allows accessing openbmc from GUI.
  - Checked the role collection and there is no change.

  - The hostconsole group is not present for readonly or operator users
    and also made sure that console access is not provided. This testing
    is done one the system and console access was tried by modifying the
