pull command is using |4- notation in yaml, which is not compatible with the list or apply commands

[basvdl]

If the query starts with an blank line, grr pull will generate a yaml file using the |4- notation. Although this is valid yaml, the list and apply commands do not work when this notation is present in the yaml files.

Query that starts with a blank line:

Will result in this expression when using grr pull

              expr: |4-
                rate(
                    node_cpu_seconds_total{mode="system"}[$__rate_interval]
                )

In this case grr list will fail:

grr list resources/dashboards/general/dashboard-mwwg8CQVk.yaml
INFO[0000] Listing 0 resources
API VERSION    KIND    UID

If I simply change |4- to |- in the yaml and rerun the list command:

grr list resources/dashboards/general/dashboard-mwwg8CQVk.yaml
INFO[0000] Listing 1 resources
API VERSION                     KIND         UID
grizzly.grafana.com/v1alpha1    Dashboard    mwwg8CQVk

The immediate workaround for this issue is to use JSON instead, so use -f json to avoid the use of YAML.

Grizzly depends upon Golang YAML parsers, and every YAML parser I've played with has some issues with Grafana dashboards, which tend to do some odd things.
