Fix flaky CLC installation in tests (#757)

Downloading the latest version often fails: 

```
Hazelcast CLC Installer (c) 2023 Hazelcast, Inc.

INFO  Creating the Home directory: /home/runner/.hazelcast
ERROR could not determine the latest version
Error: Process completed with exit code 1.
```

Added retry mechanism for CLC installation.
