zhengruifeng 052ff49acd [SPARK-30659][ML][PYSPARK] LogisticRegression blockify input vectors 
### What changes were proposed in this pull request?
1, reorg the `fit` method in LR to several blocks (`createModel`, `createBounds`, `createOptimizer`, `createInitCoefWithInterceptMatrix`);
2, add new param blockSize;
3, if blockSize==1, keep original behavior, code path `trainOnRows`;
4, if blockSize>1, standardize and stack input vectors to blocks (like ALS/MLP), code path `trainOnBlocks`

### Why are the changes needed?
On dense dataset `epsilon_normalized.t`:
1, reduce RAM to persist traing dataset; (save about 40% RAM)
2, use Level-2 BLAS routines; (4x ~ 5x faster)

### Does this PR introduce _any_ user-facing change?
Yes, a new param is added

### How was this patch tested?
existing and added testsuites

Closes #28458 from zhengruifeng/blockify_lor_II.
