Concatenates an array of {@link Publisher}s eagerly into a single stream of values
and delaying any errors until all sources terminate.

<p>
Eager concatenation means that once a subscriber subscribes, this operator subscribes to all of the
source {@code Publisher}s. The operator buffers the values emitted by these {@code Publisher}s
and then drains them in order, each one after the previous one completes.
<dl>
<dt><b>Backpressure:</b></dt>
<dd>The operator honors backpressure from downstream. The {@code Publisher}
sources are expected to honor backpressure as well.
If any of the source {@code Publisher}s violate this, the operator will signal a
{@code MissingBackpressureException}.</dd>
<dt><b>Scheduler:</b></dt>
<dd>This method does not operate by default on a particular {@link Scheduler}.</dd>

@param <T> the value type
@param sources an array of {@code Publisher}s that need to be eagerly concatenated
@param maxConcurrency the maximum number of concurrent subscriptions at a time, Integer.MAX_VALUE
is interpreted as indication to subscribe to all sources at once
@param prefetch the number of elements to prefetch from each {@code Publisher} source
@return the new Flowable instance with the specified concatenation behavior
