Fixes to markdown format of PLA tests

7. SSH into VNF 1  and make sure that the `firsttouch` and `mytouch1` files have been created.

## Automatic Placement Feature (feature 7953)

### [PLA-01] Basic Placement

_Note. The following is a basic test of PLA using a nsd with a single vnf and only two VIMs. It does therefore not capture more elaborate capabilities of the PLA module such as e.g. pinning and vld constraints._

1. Install PLA 

PLA is an optional module, install by adding --pla to install script

1. Install PLA 

   - PLA is an optional module, install by adding --pla to install script

   ```bash

   $ ./install.sh <...> --pla`

   ```

2. Create the VIMs

Create at least two VIM instances

   - Create at least two VIM instances

     ```bash

     $ osm vim-create --name <VIM_NAME> --account_type openstack --auth_url <URL> --user <USER> --password <PASSWORD> -- tenant <TENANT> --description "my description"`

     ```

The list of VIMs should be similar to e.g.:

```

   - The list of VIMs should be similar to e.g.:

     ```text

     +------------+--------------------------------------+

     | vim name   | uuid                                 |

     +------------+--------------------------------------+

     ```

3. Get the descriptors and onboard them

   ```bash

   $ wget http://osm-download.etsi.org/ftp/osm-6.0-six/8th-hackfest/packages/hackfest-basic_vnfd.tar.gz

   $ wget http://osm-download.etsi.org/ftp/osm-6.0-six/8th-hackfest/packages/hackfest-basic_nsd.tar.gz

   $ osm vnfd-create hackfest-basic_vnfd.tar.gz

   $ osm nsd-create hackfest-basic_nsd.tar.gz

   ```

4. Create the price lists for compute and transport links

Create the price list files vnf_price_list.yaml and pil_price_list.yaml

vnf_price_list.yaml should contain an entry for the vnfd to use, e.g.

```

   - Create the price list files `vnf_price_list.yaml` and `pil_price_list.yaml`. `vnf_price_list.yaml` should contain an entry for the vnfd to use, e.g.

     ```yaml

     - vnfd: hackfest-basic_vnfd

       prices:

         - vim_url: http://10.234.12.47:5000/v3

           vim_name: OpenStack2

           price: 10

      ```

Note `vim_url` and `vim_name` corresponding to step 2.

pil_price_list.yaml describes the inter-vim communication links, e.g.

```

      - Note `vim_url` and `vim_name` corresponding to step 2.

   - `pil_price_list.yaml` describes the inter-vim communication links, e.g.

     ```yaml

     pil:

       - pil_description: Link between OpenStack1 and OpenStack2

         pil_price: 5

           - OpenStack1

           - OpenStack2

     ```

Note `pil_endpoints` using VIM names corresponding to step 2.

     - Note `pil_endpoints` using VIM names corresponding to step 2.

5. Update the PLA container with price list and inventory file

   ```bash

   $ docker cp vnf_price_list.yaml $(docker ps -qf name=osm_pla):/placement/.

   $ docker cp pil_price_list.yaml $(docker ps -qf name=osm_pla):/placement/.

   ```

6. Instantiate the service using the placement engine

Use the more expensive vim for `--vim_account`.

   - Use the more expensive vim for `--vim_account`.

     ```bash

     $ osm ns-create --ns_name pla_test --nsd_name hackfest-basic_nsd --vim_account OpenStack2 --config '{placement-engine: PLA}'

     ```

7. Check VNF deployment

The VNF will be deployed to a VIM according to the content of price list.

   - The VNF will be deployed to a VIM according to the content of price list.

     ```bash

     $ osm vnf-list

     ```

```

     ```text

     +--------------------------------------+------+--------------------------------------+------------------+----------------------+--------------------------------------     +----------------+

     | vnf id                               | name | ns id                                | vnf member index | vnfd name            | vim account id                       | ip address     |

     +--------------------------------------+------+--------------------------------------+------------------+----------------------+--------------------------------------+----------------+

     | cbacb383-c2e9-4fda-b066-649165e294bc | -    | 54d36395-53cd-4b99-817b-5900f88523da | 1                | hackfest-basic_vnfd  | 576bbe0a-b95d-4ced-a63e-f387f8e6e2ce | 192.168.241.9  |

     +--------------------------------------+------+--------------------------------------+------------------+----------------------+--------------------------------------+----------------+

     ```

In this example the VNF is deployed to OpenStack1 being the cheapest VIM for the vnf
