[Feature Request] Remove need for Admin, Add Token Authentication for K8S-Bigip API REST calls

[drewboswell]

What chart am I using:
kubernetes bigip management (v2)
What version of Bigip am I using:
12.1.1
What version of the chart/images am I using
1.5.x
What is the feature you want
When using the kubernetes integration for bigip we need to:

• Restrict user rights to a specific partition
• Use a partition level role (NOT ADMIN!!!)
• Enable token-auth support in the k8s solution (admin is the only basic-auth accessor on the REST API)

Why is this important?

• A kubernetes cluster should not have free access to the bigip outside of it's own partition.

Would a ServiceAccount and respective RBAC address this requirement ?
