Shared Dataset parameter docs

Description

Parameter docs for fields used in lgb.Dataset construction

Arguments

label	vector of labels to use as the target variable
weight	numeric vector of sample weights
init_score	initial score is the base prediction lightgbm will boost from
group	used for learning-to-rank tasks. An integer vector describing how to group rows together as ordered results from the same set of candidate results to be ranked. For example, if you have a 100-document dataset with group = c(10, 20, 40, 10, 10, 10), that means that you have 6 groups, where the first 10 records are in the first group, records 11-30 are in the second group, etc.
