Supported API versions list should be sorted

[Kyrylo Romanenko]

When using some openstack command with unsupported API version,
then OSC lists available API versions. Lists is unsorted and hardly readable.

Example:
2016-10-05 16:06:45.250650 | 2016-10-05 16:06:45.249 | stderr:
2016-10-05 16:06:45.252002 | 2016-10-05 16:06:45.251 | baremetal version 1.21 is not in supported versions 1.8, 1.9, 1.6, 1.7, 1.4, 1.5, 1.2, 1.3, 1, 1.1, 1.20, 1.18, 1.19, 1.14, 1.15, 1.16, 1.17, 1.10, 1.11, 1.12, 1.13
2016-10-05 16:06:45.253311 | 2016-10-05 16:06:45.252 | Invalid baremetal client version '1.21'. must be one of: 1.8, 1.9, 1.6, 1.7, 1.4, 1.5, 1.2, 1.3, 1, 1.1, 1.20, 1.18, 1.19, 1.14, 1.15, 1.16, 1.17, 1.10, 1.11, 1.12, 1.13

Sorted output of versions would be better for usage.

Expected example of sorting: '1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24'

Patch help to sort versions in first part of output:

baremetal version 1.25 is not in supported versions: 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24

Invalid baremetal client version '1.25'. must be one of: 1.4, 1.5, 1.6, 1.7, 1.1, 1.2, 1.3, 1.8, 1.9, 1.16, 1.17, 1.14, 1.15, 1.12, 1.13, 1.10, 1.11, 1.18, 1.19, 1, 1.23, 1.22, 1.21, 1.20, 1.24

With both patches output looks as expected:
$ openstack baremetal node create --driver fake --resource-class test_resource_class --os-baremetal-api-version 1.25
baremetal version 1.25 is not in supported versions: 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24
Invalid baremetal client version '1.25'. must be one of: 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24
