Purge with Soft=true bug

[yassine-y]

Purge with soft=true is broken

// Purge instantly purges an individual URL.
func (c *Client) Purge(i *PurgeInput) (*Purge, error) {
	if i.URL == "" {
		return nil, ErrMissingURL
	}

	ro := new(RequestOptions)
	ro.Parallel = true
	if i.Soft {
		ro.Headers["Fastly-Soft-Purge"] = "1"
	}

	resp, err := c.Post("purge/"+i.URL, ro)
	if err != nil {
		return nil, err
	}

	var r *Purge
	if err := decodeBodyMap(resp.Body, &r); err != nil {
		return nil, err
	}
	return r, nil
}

this line access a non initialized map maybe! ro.Headers["Fastly-Soft-Purge"] = "1"

Thanks for raising this issue @you-yas55

I'm able to replicate the bug you've described using a test service:

p, err := client.Purge(&fastly.PurgeInput{
	URL:  "http://testing-gofastly-purge.integralist-test.com.global.prod.fastly.net/anything/foo",
	Soft: true,
})

Which triggers a panic:

panic: assignment to entry in nil map

[Integralist]

The call to new(RequestOptions) only sets a zero value for the .Headers map (which for a map type is nil) hence trying to assign a value to nil results in a panic.
