membership_policy.md misses a definition of what "active" means

[dhiller]

What happened:
When looking at the membership_policy I noticed that we are missing a definition of what active means to us.

What you expected to happen:
The membership_policy should contain a definition of "active", i.e. number of contributions required inside a defined timespan expected. All other members should therefore be considered as inactive.

Since there's a set of permissions connected to being a member of KubeVirt org (i.e. run test lanes, rehearsals etc.), we should establish a process to remove inactive members after a while to minimize security risks for the project.

Alternatively we could define "inactive" simply as no contributions over the last 12 months.

How to reproduce it (as minimally and precisely as possible):

Additional context:
Kubernetes has defined a policy for "inactive members"
They are removing inactive members after a period of 12 months from time to time (example).

Environment:

• KubeVirt version (use virtctl version): N/A
• Kubernetes version (use kubectl version): N/A
• VM or VMI specifications: N/A
• Cloud provider or hardware configuration: N/A
• OS (e.g. from /etc/os-release): N/A
• Kernel (e.g. uname -a): N/A
• Install tools: N/A
• Others: N/A
