[beatsauthextension] Add support for beats related ssl parameters to be used with otel-components

[khushijain21]

This extension supports beats' related client ssl parameters such as verification_mode , ca_trusted_fingerprint and ca_sha256 to be used with otel components using extensions

Local Testing done as follows:

receivers:
  otlpjsonfile:
    include_file_name: true
    include:
      - "./otlp-all.json"

extensions:
  beatsauth: 
    tls:
      verification_mode: full
      ca_trusted_fingerprint: "XXX"

exporters:
  debug:
    verbosity: detailed
  elasticsearch: 
   endpoints: 
    -  https://my-deployment-XXX:443
   password: XXXX
   user: elastic
   tls:
    ca_file: ./ca.crt
   auth: 
    authenticator: beatsauth  

service:
  extensions: [beatsauth]
  pipelines:
    logs:
      receivers: [otlpjsonfile]
      processors: []
      exporters: [debug, elasticsearch]

The ca.crt file contains a a self signed certificate. And when ca_trusted_fingerprint is not used, the indexing fails. The indexing is successfull on passing correct ca_trusted_fingerprint.

Looks good! I think it could do with a bit more test coverage, but otherwise LGTM.

[khushijain21]

can this PR be merged?

I'm not super close to Beats these days, so I suggest we wait for @mauri870 to take another look before merging.

Would you mind adding the extension directory into the depenabot configuration file as well https://github.com/elastic/opentelemetry-collector-components/blob/main/.github/dependabot.yml?

That would help to upgrade the testing distribution all at once. Thank you (sorry about not having written guidelines for that yet)

LGTM
