fix(helm): fixed memcached and provisioner templates to follow the same patter of specifying imagePullSecrets in the same way as the majority of the components have. Otherwise, it's make it impossible to specify image pull secrets in all the components at the same time because they are incompatible.

Previously only components expected to have image pull secrets specified in the way:
```yaml
imagePullSecrets:
  - name: pull-secret
```
but provisioner and memcached expected to have the format:
```yaml
imagePullSecrets:
  - pull-secret
```
