Fix OLM data & formatting issues

[JohnStarich]

Fixes OLM metadata so it will install properly from Operator Hub for v0.2+. Adds make tasks to assists OLM testing.
Bumps the memory limit to mitigate an OOMKilled issue when running in OpenShift 4.4 (i.e. lots of built-in secrets). Opened #199 to look into it further.

Also update TokenController to skip processing any secret not using the well-known names. e.g. secret-ibm-cloud-operator <namespace>-secret-ibm-cloud-operator
