Remove dependencies and tests that are not needed for CA / SSL

## Expected Behavior

The SDK shouldn't include test dependencies to test the behavior of other libraries or functionality that is out of the scope from the SDK.

## Actual Behavior

This PR:

[](https://github.com/dapr/java-sdk/commit/daf4c8b7030f963110f29b3c08ade14babd83c33)

Added the following dependencies that are not needed and we shouldn't have in the SDK:

```

org.bouncycastle
bcprov-jdk15on
1.70
test


org.bouncycastle
bcpkix-jdk15on
1.70
test

```
It also added complex tests in the following Test class:

[sdk/src/test/java/io/dapr/utils/NetworkUtilsTest.java](https://github.com/dapr/java-sdk/commit/daf4c8b7030f963110f29b3c08ade14babd83c33#diff-b7c65e0352b8116b33b92da139dac5fd3527fb1672f592c180a1b560651f0c78)

These tests are not necessary here because the SDK is not responsible for checking that the certificates are correctly generated. We should only test and assert that the certificates are set if the correct properties are set.

Also, all the previously existing tests are now adding the channel to an ArrayList, I would love to know the reason for doing that, this should be removed if it is not serving any purpose.

## Steps to Reproduce the Problem

## Release Note

RELEASE NOTE:

Inizia esaminando le dichiarazioni delle dipendenze per le librerie di test Bouncy Castle e sdk/src/test/java/io/dapr/utils/NetworkUtilsTest.java. Controlla le asserzioni relative ai certificati e i test esistenti che aggiungono canali a una ArrayList, quindi verifica che rimanga coperto solo il comportamento delle proprietà dei certificati di proprietà dell'SDK e che le dipendenze e il codice di test non necessari siano stati rimossi.

Scritto dal modello di indicizzazione a partire dal testo della issue.
