Configuring timeout durations in a custom ConnectionPool

[lauzadis]

We use the public constructor of ConnectionPool to create a pool with a custom keepAliveDuration, but this does not support configuring other timeouts (like readTimeoutMillis), which are all part of the internal constructor.

This means we can't simultaneously configure connect/read/write timeouts and keepAliveDuration.

For our specific use-case, here is where we configure custom timeouts, and here is where we create a custom connection pool immediately after, effectively overriding those timeouts.

Is there some way to accomplish this already? If not, I can think of a few solutions:

1. Add other timeout durations (like readTimeoutMillis) to the public constructor of ConnectionPool
2. Support configuring keepAliveDuration on the default ConnectionPool without replacing it
3. Support configuring timeout durations on an already-constructed ConnectionPool

Thanks!
