[~vozerov] done, please have a look:
* Changed config to use {{ICollection}} with support of port ranges
like {{myhost.com:200..210}}
* Deprecated {{Host}} and {{Port}}
* Implemented round-robin with global state

Pavel Tupitsyn commented on IGNITE-7282:
1) I think I agree, we should be consistent with other config APIs.
> instead of having three properties Host, Port and Endpoints, we can have
> only one - Endpoints
{{Host}} and {{Port}} are already in 2.4, do you suggest to make them obsolete
(deprecated)?
2) This property applies also when only one endpoint is defined: should we
reconnect in case when connection has dropped or not.
3) This is not an internal detail since user provides us with a list of
endpoints. They might want to know which of these provided endpoints is in use,
I think this makes the API symmetrical.

Pavel Tupitsyn commented on IGNITE-7282:
{{EndPoint}}, {{DnsEndPoint}}, {{IPEndPoint}} classes do not play well with XML
configuration, there are no parameterless contructors. We may have to switch to
our own class for that.

Pavel Tupitsyn commented on IGNITE-7282:
On the second thought, we should provide a list of host:port pairs, so multiple
hosts in a single property does not work.
Let's provide {{ICollection IgniteClientConfiguration.EndPoints}}
property in addition to existing {{Host:Port}} pair.

* No changes on server
* User specifies multiple hosts in {{IgniteClientConfiguration.Host}} (with a
comma)
* Pick a random position in the list, connect
