Dashboard/React/BasicDeploymentForm: Number precision issues in SliderParam if sliderStep is set to a floating number

[dionysius]

Describe the bug
In a deployment schema, if sliderStep property of a SliderParam is set to a floating point number the displayed slides sometimes show floating precision issues

To Reproduce
Requirements: Have a own chart repository setup with kubeapps.

1. Make a copy of the chart https://github.com/bitnami/charts/blob/master/bitnami/joomla/
2. Edit the slider schema to add the property sliderStep and set it to 0.1, e.g. this field: https://github.com/bitnami/charts/blob/master/bitnami/joomla/values.schema.json#L100
3. Upload the chart to your chart repository
4. Load your chart in kubeapps
5. Move the slider of this property and observe the results

Expected behavior
The precision of the resulting input field should always stay 1 floating point, because the sliderStep input was itself as well 1 floating point.

Screenshots




(I've manipulated the width of the input field to easier display the issue)

Thanks for reporting it! We are currently thinking of moving towards an alternative way to render the forms, more focused on a standard json schema. See the milestone: https://github.com/vmware-tanzu/kubeapps/milestone/27

We will probably tackle all the form-related issues at once, when we have enough bandwidth for it. In the meanwhile, we really welcome any PR contributions!
