sgandon ddb5be1b9d feat: optionally show logs for hooks (#699) ...

Resolves #689 

This adds a new yaml entry for the hook definition to allow the users to specifcy if they want to show the `command` logs or not.

here is an example.
```
releases:
- name: myapp
  chart: mychart
  # *snip*
  hooks:
  - events: ["cleanup"]
    showlogs: true
    command: "kubectl"
    args: ["get", "ingress"]
```
this will display the following output:
```
hook[cleanup] logs | NAME              HOSTS                          ADDRESS   PORTS   AGE
hook[cleanup] logs | catalog-gateway   tdc.foo                                  80      2d6h
hook[cleanup] logs | dataset           foobar.barr.foo.xxxxxxx.com              80      2d6h
hook[cleanup] logs | rating            fooba.barr.foo.xxxxxxx.com               80      2d6h
hook[cleanup] logs | sharing           foobar.barr.foo.xxxxxxx.com              80      2d6h
hook[cleanup] logs | tpsvc-iam-dev     foo.barr.foo.xxxxxxx.com                 80      2d6h
hook[cleanup] logs | tpsvc-iam-front   bar.barr.foo.xxxxxxx.com                 80      2d6h
