Wrong help given for nova usage command

[Abhishek Talwar]

Running nova help usage command gives you help as :

$ nova help usage

usage: nova usage [--start <start>] [--end <end>] [--tenant <tenant-id>]

Show usage data for a single tenant.

Optional arguments:
  --start <start> Usage range start date ex 2012-01-20 (default: 4 weeks
                        ago)
  --end <end> Usage range end date, ex 2012-01-20 (default:
                        tomorrow)
  --tenant <tenant-id> UUID or name of tenant to get usage for.

Running the command with tenant name doesn't give the right output.

So the help should be modified to :

$ nova help usage

usage: nova usage [--start <start>] [--end <end>] [--tenant <tenant-id>]

Show usage data for a single tenant.

Optional arguments:
  --start <start> Usage range start date ex 2012-01-20 (default: 4 weeks
                                   ago)
  --end <end> Usage range end date, ex 2012-01-20 (default:
                                   tomorrow)
  --tenant <tenant-id> UUID of tenant to get usage for.

This way the user will get to know that the command works only with tenant-id and not tenant-name.

    Wrong help for nova usage command

    nova help usage commands provides help that the command
    can be used with either tenant name or tenant ID but using
    tenant name gives wrong output.

    So, updated the help for the command so that it is shown
    that only tenant ID can be used.
