We rename path to path_regex in the ServiceProfile CRD to make it clear that this field accepts a regular expression. We also take this opportunity to remove unnecessary line anchors from regular expressions now that these anchors are added in the proxy.

Adds an endpoint, at /profiles/new that allows you to input a service name and
namespace, and download a service profile yaml template.
This will enable future work, where we can add more of the yaml customization via
a form in the dashboard, and use that data to help the user configure routes.
The `--open-api` flag is an alternative to the `--template` flag for the `linkerd profile` command. It reads an OpenAPI specification file (also called a swagger file) and uses it to generate a corresponding service profile.

Service profiles must be named in the form `"<service>.<namespace>"`. This is inconsistent with the fully normalized domain name that the proxy sends to the controller. It also does not permit creating service profiles for non-Kubernetes services.
We switch to requiring that service profiles must be named with the FQDN of their service. For Kubernetes services, this is `"<service>.<namespace>.svc.cluster.local"`.
This change alone is not sufficient for allowing service profile for non-Kubernetes services because the k8s resolver will ignore any DNS names which are not Kubernetes services. Further refactoring of the resolver will be required to allow looking up non-Kubernetes service profiles in Kuberenetes.

Add a new CLI command: `linkerd profile --template` which outputs a sample service profile yaml. Users can edit this sample and then `kubectl apply` it to add a service profile. The sample serves as "documentation by example" of what service profiles may contain.
Example usage:
```bash
linkerd profile -n emojivoto --template web-svc > web-svc-profile.yaml
# edit web-svc-profile.yaml in your favorite editor
kubectl apply -f web-svc-profile.yaml
```
