    Issue Type: Improvement  (was: Bug)

> Add meta storage metrics - size of notification futures chain, time of 
> notification application
> -----------------------------------------------------------------------------------------------
>
>                 Key: IGNITE-28398
>                 URL: https://issues.apache.org/jira/browse/IGNITE-28398
>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Denis Chudov
>            Priority: Major
>              Labels: ignite-3
>
> *Motivation*
> Sometimes we see the following:
> {code:java}
> Lease update invocation failed because of outdated lease data on this 
> node{code}
> This is logged continuously during the significant period of time.
> This means that meta storage notifications highly likely lag behind the real 
> time, which may also affect cluster safe time and maybe something else.
> I think, this may happen because of big chain of notification futures, and in 
> the case when each notification takes long time, but now we don't have any 
> metrics to see this.
>  
> *Definition of done*
> Metrics for size of notification futures chain, time of notification 
> application added.
