[Enhancement]: TLS Authentication in Backup Tool

[gifi-siby]

What would you like to be added?

I would like to add TLS support for Milvus-Backup tool

Why is this needed?

Milvus-Backup currently doesn't support TLS and thus, I am not able to connect using certificates.
We are using self signed certificates for authentication in Milvus like below:

uri = "https://ibmlhadmin:password@localhost:19530"
user = "user"
password ="password"
client = MilvusClient(
                      uri=uri,
                      user=user,
                      password=password,
                      secure=True,
                      db_name="default",
                      server_pem_path='/root/tls/cert.crt',
                      server_name='localhost',)

Anything else?

This change has been released in v0.4.30, but was not included in main due to conflicts. Will be cherry-picked to main later.

The related commits have been merged into the main branch and will be included in the upcoming v0.5.0 release. However, to ensure a clear distinction from the mTLS-related parameters, I have renamed the original configuration key tlsCertPath to caCertPath in the configuration file.
