Change looks good to me, let's wait for tests.
> Cache SSL contexts in SslContextFactory

> Key: IGNITE-12753
> URL: https://issues.apache.org/jira/browse/IGNITE-12753
> Project: Ignite
> Issue Type: Improvement
> Reporter: Denis Mekhanikov
> Assignee: Denis Mekhanikov
> Priority: Major
> Fix For: 2.9

> Time Spent: 10m
> Remaining Estimate: 0h
>
> When SSL is enabled in a cluster, SslContextFactory#createSslContext is
> created every time when connections between nodes are created. It involves
> accessing key storage on disk. It may slow down creation of new communication
> connections and block striped pool threads if disks are slow.
> SSL contexts are stateless and can be shared between threads, so it's safe to
> create an SSL context once and use the same instance every time.
