[4.4.0 Alpha] MTLS support for production and sandbox bug in distributed setup

[SachiniSiriwardene]

Description

When tested in a distributed setup, even when the certificate is sent in the request as a header (becuase TLS terminates at load balancer), the following error is given:
{"code":"900901","message":"Invalid Credentials","description":"Invalid Credentials. Make sure you have provided the correct security credentials"}
Work as expected in a local setup.

Steps to Reproduce

1. Create and publish an API and enable MTLS in transport level security.
2. Add the configs as mentioned in [(https://apim.docs.wso2.com/en/4.4.0/design/api-security/api-authentication/secure-apis-using-mutual-ssl/#using-mtls-header-to-invoke-apis-secured-with-mutual-ssl)] to deployment.toml.
3. Send a request with the public certificate in a header.
4. Invalid credentials error is given but should result in a successful request.
