Stardardization of naming conventions for labels and resource names

### Issue1: Chart.yaml
Ref. https://helm.sh/docs/topics/charts/
An issue request to update appVersion in Chart.yaml so that APP VERSION is listed
```
helm list --namespace vault
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
vault vault 1 2020-04-14 16:30:40.1957995 +0200 CEST deployed vault-0.5.0
```

### Issue2: Standard labels convention
An issue request to add these labels in ALL resources, including :

* ClusterRole
* ClusterRoleBinding
* Deployment
* MutatingWebhookConfiguration
* Service
* ServiceAccount
* ConfigMap
* PodDisruptionBudget
* RoleBinding
* StatefulSet

#### Standard labels
```
app.kubernetes.io/name: {{ include "vault.name" . }}-#thesuffix#
app.kubernetes.io/description: {{ include "vault.description" . }}
app.kubernetes.io/instance: {{ .Release.Name }}
app.kubernetes.io/managed-by: {{ .Release.Service }}
app.kubernetes.io/version: {{ .Release.Version }}
app.kubernetes.io/component: "vault-helm"
app.kubernetes.io/managed-by: "https://github.com/hashicorp/vault-helm"
app.kubernetes.io/part-of=vault
app.kubernetes.io/vendor=Hashicorp
helm.sh/chart: {{ include "vault.chart" . }}
```
#### Example in the comment areas for "extraLabels" i values.yaml
```
customerdomain.com/app-role="vaultRole"
customerdomain.com/contacts="FirstName LastName Or EmailAddress"
customerdomain.com/environment="prod Or staging Or test Or dev"
customerdomain.com/team=services
customerdomain.com/tier="backend Or frontend Or cache"
```

### Issue3: Update Suffix on resource names
An issue request to add suffix on ALL resources names **metadata.name**

| Template File | Resource | Current | New |
| ------ | ------ | ------ | ------ |
| server-disruptionbudget.yaml | PodDisruptionBudget | vault | vault-pdb |
| injector-serviceaccount.yaml | ServiceAccount | vault-agent-injector | vault-agent-injector-sa
| server-serviceaccount.yaml | ServiceAccount | vault | vault-sa |
| server-config-configmap.yaml | ConfigMap | vault-config | vault-cfm |
| injector-clusterrole.yaml | ClusterRole | vault-agent-injector-clusterrole | vault-agent-injector-clr |
| injector-clusterrolebinding.yaml | ClusterRoleBinding | vault-agent-injector-binding | vault-agent-injector-clrb |
| server-clusterrolebinding.yaml | ClusterRoleBinding | vault-server-binding | vault-server-clrb |
| server-discovery-role.yaml | Role | vault-discovery-role | vault-discovery-rle |
| server-discovery-rolebinding.yaml | RoleBinding | vault-discovery-rolebinding | vault-discovery-rleb |
| injector-service.yaml | Service | vault-agent-injector-svc | vault-agent-injector-svc |
| server-ha-active-service.yaml | Service | vault-active | vault-active-svc |
| server-ha-standby-service.yaml | Service | vault-standby | vault-standby-svc |
| server-headless-service.yaml | Service | vault-internal | vault-internal-svc |
| server-service.yaml | Service | vault | vault-svc |
| ui-service.yaml | Service | vault-ui | vault-ui-svc |
| injector-deployment.yaml | Deployment | vault-agent-injector | vault-agent-injector-dpl |
| injector-mutating-webhook.yaml | MutatingWebhookConfiguration | vault-agent-injector-cfg | vault-agent-injector-mwc |

Start with Chart.yaml and the listed templates, including server-disruptionbudget.yaml, injector-serviceaccount.yaml, server-serviceaccount.yaml, and the remaining resource files in the naming table. Review how metadata labels and names are currently defined across all listed resources. Done means appVersion appears in helm list output, standard labels are present on every named resource, and the requested name suffixes are applied consistently.
