RUMM-1151 Use the Local first-party host detector

[xgouchet]

What does this PR do?

Ensure the local first party hosts provided in the OkHttp Interceptors are actually used.

Fixes #513

Additional Notes

We also removed the warnDeprecated calls that existed and weren't not removed in the un-deprecation of the related constructors

Do you want to update the Sample App too by adding the tracedHosts to RumInterceptor or you want to do this in a second PR ?

[0xnm]

so I guess this is the main reason of the issue?

[mariusc83]

Mostly this one but sometimes our clients can have multiple OkHttp clients and they want to be able to configure separated traced hosts for them. Having this in mind we need a global traced hosts entry + the possibility to add custom traced hosts/RumInterceptor and for that we were using the localFirstPartyHostDetector which was not used anymore.
