fix: Change directory structure to match hackfest

## Functional test folder

This functional test can be found in folder `src/tests/netx22-p4/`. 

This functional test can be found in folder `hackfest/p4`

## P4 source and Mininet topology

This test is designed to operate with a mininet deployment that contains 2 hosts and a BMv2 switch, such a topology can be found in the 'src/tests/netx22-p4/mininet' folder.

Additionally the P4 source code, along with its compiled artifacts are present in the 'src/tests/netx22-p4/mininet' folder.

## Deployment and Dependencies

start-simple: _start

```

And copy the topology file from ~/tfs-ctrl/src/tests/netx22-p4/mininet/topo-simple.py to the ~/ngsdn-tutorial/mininet/ directory.

## Test Execution

In another terminal cd to the teraflow directory and run the following

```

src/tests/netx22-p4/setup.sh

hackfest/p4/setup.sh

```

This will copy the p4 artifacts to the device pod.

Then you can bootstrap the device to the Teraflow Controller

```

src/tests/netx22-p4/run_test_01_bootstrap.sh

hackfest/p4/run_test_01_bootstrap.sh

```

Install the required rules to the p4 switch

```

src/tests/netx22-p4/run_test_02_create_service.sh

hackfest/p4/run_test_02_create_service.sh

```

You should now check the mininet terminal. The two hosts should be pinging each other as intended.

You can remove the rules from the p4 switch

```

src/tests/netx22-p4/run_test_03_delete_service.sh

hackfest/p4/run_test_03_delete_service.sh

```

The two hosts on the mininet terminal, should stop pinging.

And remove the device from the Teraflow Controller

```

src/tests/netx22-p4/run_test_04_cleanup.sh

hackfest/p4/run_test_04_cleanup.sh

```
