CSCuz71936 - Invalid reject cause in Attach Reject due to ESM PDN Connectivity Reject

In 17.5, 18.x, 19.x (19.0 to 19.4) and 20.x releases, the EMM cause code #15 (No suitable cells in tracking
area) and ESM cause as #31 are sent in the Attach Reject when the subscriber does not have an LTE/EPS

New Behavior: In releases 19.5, 21.0 and beyond, the behavior of MME is modified to accustom to the needs
of all customers. New configurable options odb packet-services emm-cause-code and odb roamer-to-vplmn

Two new keywords odb packet-services emm-cause-code and odb roamer-to-vplmn emm-cause-code are
introduced as part of local-cause-code-mapping CLI command in the Call Control Profile configuration
