Add process to remove maintainers that don't fulfill their duties
Add process to remove maintainers that don't fulfill their duties

When asking CNCF for support due to reduced community activity we stumbled upon a problem,
governing board was surprised that project is unmaintained as there is so many maintainers listed for the project.

Feedback was to improve accuracy of maintainers list so it reflects only active maintainers.
Self nominating process it not enough and we need to start enforcing
moving maintainers to emeritus status. Period of 12 months to take maternity leave into account.
