[Property Name] SweepInterval [Default Value] 5 minutes [Description] 
The frequency in which the container will sweep the pool and evict expired instances. Eviction is how the IdleTimeout, MaxAge, and pool "flush" functionality is enforced. Higher intervals are better. Instances in use are excluded from sweeping. Should an instance expire while in use it will be evicted immediately upon return to the pool. Effectively MaxAge and flushes will be enforced as a part of normal activity or sweeping, while IdleTimeout is only enforcable via sweeping. This makes aggressive sweeping less important for a pool under moderate load. Usable time units: nanoseconds, microsecons, milliseconds, seconds, minutes, hours, days. Or any combination such as "1 hour and 27 minutes and 10 seconds"
