[SYSTEMDS-2627] Federated mmchain instruction for lmCG, MLogreg, GLM

This patch adds a federated mmchain instruction for a common
matrix-vector multiplication chain as it appears in the inner loop of
lmCG, Mlogreg, and GLM. It also includes a fix for more robust
instruction manipulation, and a GLM federated test.

Furthermore, we now use a slightly better approach for deciding between
conf-only and context spark cluster analysis to avoid unnecessary spark
context creation in local mode (which sometimes interferes with netty
port allocation in federated tests).
