ao configmap: fixes for handling boolean and numeric values

[galmasi]

Summary

This is a small fix to allow the helm-generated configmap to accommodate boolean and numeric values -- it forces extra quotes into the configmap.

How to produce the error

The following snippet in values.yaml will cause helm deployment failure. It does not matter whether the word false is quoted, doublequoted, escaped in any way -- as long as it's recognizable as a boolean the failure will happen.

Similar problems happen with any value that is JSON/YAML parseable as an integer.

global:
  configmap:
    configParams:
      KEYLIME_TENANT_REQUIRE_EK_CERT: false

Gist of the fix

Produce extra quotes in the configmap template[s] to prevent parsing of affected values as anything but string.

Affected locations

Two places I noticed that are using .Values.global.configmap.configParams:

• charts/keylime-init/templates/ca-job.yaml -- global environment variables used to direct CA generation
• templates/configmap.yaml -- the actual copying of environment variables into the keylime configmap

Why we need this

I cannot start to produce meaningful CI tests without disabling EK cert requirements on AWS machines (since AWS TPMs don't have EK certificates). Expect a second, much larger PR for meaningful CI tests with AWS EC2 VMs as soon as this is merged.

Obvious but sorely needed fix. LGTM
