Enable counter_enabled.py to support batch mode (#3709)

Browse source 
* Enable counter_enabled.py to support serial mode

Enable counter_enabled.py to support batch playbook executions using the serial tag in plays. Currently, the host counter gets reset at the beginning of every task. However, during batch executions we want it to keep track of the previous batch executions and print the host counter based on the previous runs. This proposal keeps track of how many servers have been updated in previous batches and starts the host counter at that tracked value.

```
- hosts: allthethings
  gather_facts: no
  serial:
    - 3
    - 15%
    - 20%
    - 35%
    - 55%
    - 90%
    - 100%
  tasks:
    - name: Ping Hello!
      ping:
        data: "Hello!!!!"
```
