Centralize SSL configuration and certificate provider factory

[chenqi0805]

Is your feature request related to a problem? Please describe. The TLS/SSL config has not been unified across plugins (otel-trace-source, http, peerforwarder). It should be unifiable so that all plugins could reuse the same config and CertificateProviderFactory.

Describe the solution you'd like We need to sort out all necessary TLS/SSL config parameters and document them in a separate TLS/SSL module

Describe alternatives you've considered (Optional) A clear and concise description of any alternative solutions or features you've considered.

Additional context Add any other context or screenshots about the feature request here.

I believe we can resolve this via the enhanced plugin support. This also means that new plugins can provide new implementations.

This can be solved using plugins similar to what Data Prepper does for authentication (see #464).

Example for the file-based certificates:

http:
  ssl: true
  certificate:
    file:
      certificate_path: /usr/share/my/path/public.cert
      private_key_path: /usr/share/my/path/private.key

Example for the S3-based certificates:

http:
  ssl: true
  certificate:
    s3:
      certificate_uri: s3://mybucket/my/key/public.cert
      private_key_uri: s3://mybucket/my/key/private.key

Example for the ACM-based certificates:

http:
  ssl: true
  certificate:
    acm:
      arn: arn:...
      passphrase: secret
