DDC-3407: add possibility to prevent some entitiy methods from being proxied

[doctrinebot]

Jira issue originally created by user backbone:

This is for optimization of lazy loading, when using entity methods that operate only on identifier values.

This issue is partially addressed via:
ba38f3e

But it makes assumptions about a certain code style, that is for an "id" identifier property the getter is named "getId". but some code styles prefer "getID".

It would be nice to have an annotation like @Orm\SkipProxy (or equivalents for xml/yaml) to mark a method that should not be proxied.

Comment created by @Ocramius:

I wouldn't implement it that way. I'm actually building something (non-trivial) at Ocramius/ProxyManager#192 and Ocramius/ProxyManager#159, but it will take some time to get there, and also to get doctrine to use that component to generate proxy classes.

@Ocramius Is their any update on this? From what i have seen the ProxyManager implemented the needed groundwork quite a while ago, are their any plans to make them available in the orm?

Hmm, is it better to do a broad/generic "non-initializing methods" feature, or would it be better to have a narrower way to specify "this method is a primary-key getter"?

[backbone87]

well if you use the proxymanager of ocramius the lazy loading is done on accessing props not methods

#1241 is attempting to solve this issue as well

Solved in #6719
