MinConnections can not be configured on a specific ConnectionPoolSettings

[RustedBones]

I am writing a small library that uses the akka-http host connection pool client to interact with an external system.

For this library, I don't want to use the default akka.http.host-connection-pool configuration but a very specific one. This to ensure that other usage of Http().cachedHostConnectionPool(...) in the final application do not use the same pool configuration as the library.

To do this, I've done the following:

private val connectionPoolSettings = ConnectionPoolSettings(system)
    .withMaxConnections(maxConnections)
    .withMaxOpenRequests(maxConnections)
    .withMaxRetries(maxRetries)

This seems to be the easiest way to go, because it allows using the default settings and only overwrite the interesting values.

However, ConnectionPoolSettings does not provide a modifier for minConnections. I suppose this has just been forgotten.
