sidecar support https and basic auth access to Prometheus

[liangli1213]

Since Prometheus version 2.24, we can configure basic authentication and TLS for Prometheus, in my case, the Prometheus provide service directly to the whole internal network, so we enable login credential and TLS (we don't want everyone access Prometheus and username/password transmitted with plain text), and meanwhile we need configure thanos sidecar in same Prometheus (we have multiple Prometheus).

The requirement is:

1. Provide an option to set up username/password used for Prometheus's login
2. Provide an option like --insecure_skip_verify to skip verify expired certificate

We definitely need this. Help wanted.

@Namanl2001 Yes, please go ahead.

Acceptance Criteria:

• User can configure Auth and TLS option for internal Prometheus client that sidecar uses. Ideally we can reuse other Auth and TLS options we have e.g for Alertmanager

We could use similar configuration to: https://thanos.io/tip/components/rule.md/#configuration
