auto-generate the cli menu in docs

[susanev]

right now the cli menu in docs is controlled from this manually maintained file...
https://github.com/pulumi/docs/blob/master/config/_default/menus.yml

we instead want to do this over in
https://github.com/pulumi/pulumi/blob/master/pkg/cmd/pulumi/gen_markdown.go

so for every top-level command, directly under pulumi we would want to add this to its frontmatter

cli:
    weight: 2
    parent: commands

giving everything a weight of 2 will cause hugo to order them alphabetically

the pulumi command is a special case and we want it to h ave a weight of 1 so it always appears at the top

cli:
    weight: 1
    parent: commands

this should not be added for sub commands, e.g., https://www.pulumi.com/docs/cli/commands/pulumi_stack_select/
