[REQ] [kotlin-client] Add support for OkHttp3 to support Android API 4.X #4007
Description
Is your feature request related to a problem? Please describe.
In #3504 the version of OkHttp version was bumped from 3.14.2 to 4.0.1.
This has a side effect that the Kotlin-client no longer supports Android 4.X version, it only supports Android 5.0 and upwards, because OkHttp 4.X only supports Android 5.0 and upwards.

But the Android 4.X version still represents 10% of all Android devices, and some companies still need to support those devices.

I'm not sure if this change was an accident, but it would be great if Kotlin-client supports Android 4.X.
Describe the solution you'd like
The solution that I propose Is to support both OkHttp 3 and 4 and give the flexibility to the user to choose which one is best for them.
Describe alternatives you've considered
There are two other alternatives:
- Support only OkHttp3 and drop OkHttp4 and this would allow to support Android 2.3.X +.
- Continue to support only OkHttp4 and support only Android 5.X +, and drop support for 10% of all Android. Not ideal to a lot of companies.
I think that support both OkHttp3 and OkHttp4 is the preferable approach because of the flexibility it gives and it shouldn't create a lot complexity.
