[ignite] Add Apache Ignite clients 'ignite' and 'ignite-sql'

[isuntsov-gridgain]

Hi,
Could you please add AI clients (https://ignite.apache.org) from my PR to your repository?
We've added:

• ignite directory that contains clients, tests, and config
• ignite section in pom.xml

Also Apache Ignite clients was added to the DATABASES list (ycsb script).

Thanks!

@busbey please take a look at my PR. I've finished work with requested changes.

Note to self when we squash this for merge:

@author Sergey Puchnin
@author Taras Ledkov
@author Oleg Ostanin

I think those author names have to include email addresses if we want github to attribute things properly. I can probably get them from the current commit history.

I presume some of these changes are due to how github is handling diffing a merge. let me see if I can do this faster with a local checkout.

@isuntsov-gridgain would you prefer the author tag be for the gmail address that shows up in the current list of commits or the gridgain email address that shows up?

@isuntsov-gridgain I have a few changes I'd like, but they're all small things. I've got this PR ready to merge as a squashed-and-rebase, so I'd like to proceed and then file a follow-on issue with the stuff that should get changed. would that be okay with you?

@busbey I guess it should be emails from the commit list.
