You have to change the default Azure linux configuration to resolve the problem. It can be achieved via edit of the default configuration file available on the provisioned VM as /etc/waagent.conf

Changing of the default value of Provisioning.MonitorHostName from

{code}
Provisioning.MonitorHostName=y
{code}

to 

{code}
Provisioning.MonitorHostName=n
{code}

Changing of the default value from Y (yes) to N (no) will prevent the agent from detecting the hostname change and initiating the network disruption. The reported behavior 
{code}
Provisioning.MonitorHostName:
Type: Boolean
Default: y

If set, waagent will monitor the Linux virtual machine for hostname changes (as returned by the "hostname" command) and automatically update the networking configuration in the image to reflect the change. In order to push the name change to the DNS servers, networking will be restarted in the virtual machine. This will result in brief loss of Internet connectivity.
{code}

is described in the Azure docs - https://docs.microsoft.com/en-us/azure/virtual-machines/virtual-machines-linux-agent-user-guide
