Added compiler params support in keyvi cli

@hendrikmuhs

Fixes #214
Decided do not expose memory_limit param for now and use default to avoid backward compatibility issue later on.

A merge conflict is not avoidable as you make use of the API to be changed for 0.2

So if that isn't a super-urgent bug, it would be better to fix it in the 0_2_cleanup branch and get 0.2 ready asap.

Coverage remained the same at 86.698% when pulling a86e84c on narekgharibyan:keyvicli_compiler_options into f641487 on cliqz-oss:master.

@hendrikmuhs
I didn't get what merge conflicts you meant.

[hendrikmuhs]

I mean this:

dictionary = pykeyvi.KeyOnlyDictionaryCompiler(GB, params)

This is deprecated in 0.2.

Not a big deal, but it means I or you have to change it for 0.2 again. That's why I think non-super-urgent features should go into 0_2_cleanup.

[narekgharibyan]

Sure! That's not a problem.
Moreover once we merge this PR into master. I'll merge master into 0.2 branch with appropriate fix so the fix will be already there.

[hendrikmuhs]

ok.
