Add opt-in support for insecure cipher suites in TLS config

Is your feature request related to a problem? Please describe.

There are times, typically when working with legacy solutions, when being able to support an insecure TLS cipher suite is required. Go has a list of insecure (but still better than nothing) cipher suites that are available, but currently the collector is only pulling in the fully "supported" cipher suites. Having an opt-in config to include the insecure ciphers would expand the range of supported data sources.

Describe the solution you'd like

Add an additional config parameter to the TLS config to allow users to opt-in to including the cipher suites returned by InsecureCipherSuites() in go.

More detail for anyone wanting to implement this: it sounds like it would involve adding a field in this struct to enable this function to search for ciphers in tls.InsecureCipherSuites() in addition to tls.CipherSuites().
