Using teflo > 1.2.0 causes an exception when using vars-data

[Dannyb48]

As of 1.2.1 whenever we run the following command:

teflo run -s tests/teflo_sdf/osp_dev_stack_deploy.yml --workspace ./ --vars-data playbooks/group_vars/autobot.yml --vars-data playbooks/group_vars/dev.yml --task provision --labels ceph --labels ceph_vols

We see the following error:

In order to work around this we need to rollback and pin teflo to 1.2.0. I think this has to do with the recent changes for PR #76

[rujutashinde]

I will look at this one

[rujutashinde]

The issue arises when we are trying to recursively replace the variables in the variable file, and the value to be replaced is a list instead of a string
e.g. below the devices is resolved as a list [/dev/vdc] , string.replace operation does not like the replacement value to be a list. A string is expected

 devices:
  - /dev/vdc
disk_wipe_disks: "{{ devices }}" 

[Dannyb48]

@rujutashinde Good Catch! Yeah so I assume that utility should probably take into account check whether the type is, str, list, and dicts
