-------------------------------------------

             Summary: Add Java method to create a cache from a template
                 Key: IGNITE-11141
                 URL: https://issues.apache.org/jira/browse/IGNITE-11141
             Project: Ignite
          Issue Type: Task
            Reporter: Stanislav Lukyanov


Currently cache templates can only be used via REST or SQL: https://apacheignite.readme.io/docs/cache-template.
It seems reasonable to add the same functionality to Java.

The most flexible way would probably be to add a method like `cacheConfiguration(String)`
that would return a configuration of a template with the given name. Then to create a cache
from a template one would write code like this
{code}
CacheConfiguration cfg = ignite.cacheConfiguration("myTemplate");
cfg.setName("myCacheFromTemplate");
ignite.createCache(cfg);
{code}

As a bonus, the `cacheConfiguration(String)` method may work with regular caches too. For
them it would be a shortcut for `ignite.cache("myCache").getConfiguration()`.
