Ansible deployement failed for scala 2.13

## Environment details:

* Local deployment with ansible
* Docker version 20.10.17, build 100c701
* Ubuntu 20.04

## Steps to reproduce the issue:

I followed the steps listed in [Ansible deployment](https://github.com/apache/openwhisk/blob/master/ansible/README.md).
CouchDB is set up without any issue.

## Provide the actual results and outputs:

When building with scala 2.13, `./gredlew distDocker` only gave warnings. However
`ansible-playbook -i environments/localopenwhisk.yml` failed with error
```yml
fatal: [controller0]: FAILED! => {"attempts": 12, "changed": false, "elapsed": 0,
"msg": "Status code was -1 and not [200]: Request failed: ",
"redirected": false, "status": -1,
"url": "https://172.17.0.1:10001/ping"}

Status code was -1 and not [200]: Request failed:
```
And `docker ps` shows that the `controller0` is constantly restarting every 1 min.

`/tmp/wsklogs/controller0/controller0_logs.log` shows the error below
```java

This error doesn't occur with scala 2.12.

## Additional information you deem important:
- `scala.collection.convert.DecorateAsJava` is deprecated in Scala [2.12.2](https://www.scala-lang.org/api/2.12.2/scala/collection/convert/index.html) and removed in scala [2.13.0](https://www.scala-lang.org/api/2.13.0/scala/collection/convert/index.html)

- At first, I thought the issue is caused by pureconfig 0.11.1 not supporting 2.13. But it's not the [case](https://github.com/pureconfig/pureconfig/issues/483#issuecomment-502262722)

Just out of curiosity, while building with scala 2.13, there are more than 800 warnings about deprecations. Based on this [thread](https://github.com/apache/openwhisk/issues/4741), it seems that upgrade to 2.13 is not full completed. I am wondering if supporting scala 2.13 is still being considered or OW is moving towards scala 3.
