URL: https://github.com/apache/druid/pull/11743
### Description
Current Integration test uses 1024-bit RSA key to generate certificates for
TLS. There're warnings when generating such RSA keys or running docker images.
The warnings show as follows:
```
<druid> uses a 1024-bit RSA key which is considered a security risk. This
key size will be disabled in a future update.
```
These warnings are noisy information when handling IT test case build
failures such as #11663 . So I upgrade the length of RSA key from 1024 to 4096
to eliminate all of these warnings.
There're also wanings about use of keystore format as follows
```bash
The JKS keystore uses a proprietary format. It is recommended to migrate to
PKCS12 which is an industry standard format using "keytool -importkeystore
-srckeystore client.jks -destkeystore client.jks -deststoretype pkcs12".
```
I also change the format of keystore from JKS to PKCS12 to eliminate these
warnings.
