Move java based services to 1.8.1. Systems: Update TMS settings.

[scblack321]

Changes for move of all java based services to version 1.8.1: SK, Systems, Files, Apps, Jobs, Meta.
Update TMS settings for systems, including switching the client key to a kubernetes secret.
Also see PR #432

Most settings are in place, see PR #408.
However, setting systems_tms_client_secret should be stored as a k8s secret and not directly as an env var in the deployment file.
Also, it appears that the conditional {% if systems_tms_enabled is defined %} may not be working as expected.

Test the conditional and fix as needed. Or, consider removing the conditional and having all settings in place
all the time. The default for systems_tms_enabled would be false.
