* Allow non-JSON custom webhook templates, provided they render as valid JSON
Previously, both the provided template _and_ the rendered template had
to be valid JSON in order for validation to pass. This was unnecessarily
restrictive: really, only the rendered template needs to be valid JSON.
It also disallowed using templates such as:
{
"labels": {{ alert_payload.labels | tojson }}
}
even though this would be valid JSON after rendering.
This commit relaxes the validation of custom webhook templates so that
they don't need to be valid JSON, provided that the rendered template
_is_ valid JSON. This is checked using a dummy dictionary of render
params, which use a constant string for the `alert_group_id` field
and a `defaultdict(dict)` for the `alert_payload` field. This should
permit templates like the one above, but still deny templates such as
{
"labels": {{ alert_payload.labels }}
}
which would otherwise fail later if `labels` is not valid JSON.
This should resolve#638.
