Autocreate namespace if not present

[anvouk]

Is your feature request related to a problem?
Yes

Which solution do you suggest?
One of the following:

• Add an extra optional flag like ensureNamespace: true to enable this.
• Add a global config/env var to enable this for all deployment
• Change the default behaviour to automatically do this

IMHO the first option is nicer.

Which alternative solutions exist?
hooks but are very verbose and overkill for a task that needs to be executed only once.

Additional context
in my case i have the following (which is part of a bigger file):

version: v1beta9
deployments:
- name: pgadmin
  namespace: management
  helm:
    chart:
      name: pgadmin4
      repo: https://helm.runix.net/
      version: 1.2.25

however, when somebody runs it for the first time devspace aborts because no namespace management exists.

This is not really a problem for Kustomization/manifests since it can be added inside, but for helm charts deployments the only solutions I found are:

1. add an hook which calls a yaml with the namespace definition inside before all deployments. (cannot simply use kubectl create ns management because it's not idempotent)
2. have a separate deployment only for setup stuff.

I personally don't find neither solutions very appealing nor following k8s style.

Any suggestions?
