Onyxia fails to parse some manifests

[olevitt]

Since the latest dependencies bump it seems Onyxia fails to parse some manifests. I'm trying to reproduce

#247 is just a workaround, preventing crash but failing to retrieve URLs due to not being able to parse some manifests.
This issue is therefore still relevant

Do you have some example manifests?

[olevitt]

Not sure what exactly triggers the parsing fail but it seems some manifests that are ok with Helm / Kubernetes are not for the parser Onyxia-API (indirectly) uses.
It seems to be edge cases like this one : https://github.com/InseeFrLab/helm-charts-interactive-services/issues/115

command:
            - sh
            - -c
            - |

This does not make much sense in the real life (it was due to a bug in the package) but it's nonetheless allowed by both Helm and Kubernetes so it can happen in real life.
Not sure we can do much to tweak the parser fabric8's kubernetes client so I'm really not hopeful we can solve this issue but at least I added a workaround so that the request does not fail, only the URL won't be retrieved.
