Enhance persistent store paths: new persistent store folders naming

[Dmitriy Pavlov]

Hi Igniters,

Issue for improve persistent store paths
https://issues.apache.org/jira/browse/IGNITE-6285 has been resolved. Thanks
to Alexey G. and Yakov for review.

Details of change are available in wiki
https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood#IgnitePersistentStore-underthehood-Foldersstructure

Ignite has now new style persistent store sub folder naming. Internal
folder names are based on randomly generated consistent ID.

Existing instances will be running with existing folders. Same for manually
set consistent ID, in this case configuration parameter is used.

Sincerely,
Dmitriy Pavlov

Hi Dmitriy,

Good improvement and right in time, thanks!

Thinking of a high level documentation, the user has to know:
* how to start nodes from different clusters on a single box. They need to specify unique paths for storage files.
* how to tackle the error described as Option 3 on wiki.
* how to bind storage files to specific node instance (consistent ID option).

Could you put all this together under this doc section?
https://apacheignite.readme.io/v2.2/docs/ignite-persistence-23#section-configuration <https://apacheignite.readme.io/v2.2/docs/ignite-persistence-23#section-configuration>

That page is hidden and will be released along with 2.3. Provided you with required permissions.

Please send me for review once you’re ready.

Hi Denis,

Thank you for providing access.

Unfortunately I will not be able to start description of this change before
16 Oct. Is it OK?

Alternatively can someone from the community pick up this change? All
details, algorithm and code references are provided in
https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood#IgnitePersistentStore-underthehood-Subfoldersgeneration
(in expandable section).

Sincerely,
Dmitriy Pavlov
