WIS 1.x Metadata KPI report

[maaikelimper]

A first version of the WIS Metadata KPI report is available here:
WCMP_KPI_report_April2022.pdf

I open this issue to invite feedback and suggestions for improvement.
Also I'm wondering:

• How often should this report be generated ?
• Who should this report be shared with ? (and how)

Great work @maaikelimper ! @wmo-im/tt-wismd please take a look and provide comments.

How long does the report generation take? Perhaps a monthly report is an initial target, to be posted on wmo.int.
