> Add metric indicating that page eviction has started due to DataRegion memory
> pressure

> h1. Description
> In in-memory clusters, when a data region reaches its {*}maxSize{*}, Ignite
> starts page-based eviction. At the moment this condition can only be observed
> in logs via the following warning:
> {code:java}
> Page-based evictions started. Consider increasing 'maxSize' on Data Region
> configuration{code}
> (this message is logged from
> {*}IgniteCacheDatabaseSharedManager#warnFirstEvict{*}).
> However, there is no metric indicating such conditions, which makes it
> difficult to monitor eviction pressure using monitoring systems.
> h1. Proposed change
> Introduce a new boolean metric that becomes true when page eviction is
> triggered due to data region memory pressure.
