Add a print method for H2OSegmentModel object type in R

[exalate-issue-sync]

Currently, it just prints something like this (default S4 class print is to just print all slots):

{noformat}> models
An object of class "H2OSegmentModels"
Slot "segment_models_id":
[1] "GBM_segment_models_R_1585732049703_2"{noformat}

{code:r}> models
Segment Models ID: GBM_segment_models_R_1585799836187_2
Individual Segment Models:
