Sometimes got 'Unexpected end of stream' on android with OkHttp client

[Alex009]

sometimes we got "Unexpected end of stream" error on android. we fix it by

fun provideHttpEngine(): HttpClientEngine? {
    return OkHttp.create {
        config {
            retryOnConnectionFailure(true)
        }
    }
}

it can be good for include into moko-network
