[ClusterLabs] fence_azure_arm flooding syslog

Sorry, this typo was only in my mail because I anonymized in- and output.

The issue only occurs when I add the parameter "network-fencing=on".

WARNING:msrestazure.azure_active_directory:Keyring cache token has failed:
No recommended backend was available. Install the keyrings.alt package if
you want to use the non-recommended backends. See README.rst for details.

pcmk_host_list is used by Pacemaker to limit which hosts can be fenced by
the STONITH device, so you'll have to use the plug parameter for testing.
Pacemaker uses it internally when it fences a host, so you wouldnt use plug=
as part of the pcs stonith create command.

It seems like the issue might be the space in "pcmk_host_list= node01".
