Make common XGBoost parameters in agreement

[exalate-issue-sync]

Since XGBoost has two names for certain parameters (such as eta and learn_rate), if the user updates only one it becomes confusing which value was actually used.

In the example below, it is confusing if learn rate of 0.1 was used or learn rate of 0.3.

{code:R}

xgboost@allparameters$learn_rate
[1] 0.1
xgboost@allparameters$eta
[1] 0.3
{code}

Could we update the parameters of XGBoost so that the values are the same for parameters that are referring to the same thing?

Jan Sterba commented: this was already done one way, implemented the sync also the other way
