utils-test:Add running htx-cmdline stress_type and fix invalid sequence
This patch can be used to run htx mdts stress_type using htxcmdline tool Additionally, this patch fixes DeprecationWarning of invalid escape sequence 'x' W605
This patch introduces the following changes:
Allow running of different stress types in different vms based on stresstype%s parameter if provided in the cfg file, where %s is the name of the vm. This will allow us to introduce additional types of stress in the future. If the stresstype%s paramter is not provided, then the default stress_type will be used.
Define a new function load_htxstress_tool() to run htxcmdline tool in the guest. This function will be called whenever stress_type_vmname = htxcmdline_in_vms. The user can provide the link to the .rpm/.deb package and the function will handle the installation, followed by the running of the htxcmdline tool by using the htxcmdline_args parameter, all provided by user in the cfg file.
