fix(surveryor): make configmap fully agnostic

[Kriys94]

This PR:

• makes the ConfigMap name prefixed by the release name. With the current implementation we cannot deploy 2 surveryor chart in the same namespace
• Able to pass any yaml to the configmap such that we can fit the json output depending of the user need.

  {
  "name":       "my service",
  "topic":      "email.subscribe.>",
  "jwt":        "jwt portion of creds, must include seed also",
  "seed":       "seed portion of creds, must include jwt also",
  "credential": "/path/to/file.creds",
  "nkey":       "nkey seed",
  "token":      "token",
  "username":   "username, must include password also",
  "password":   "password, must include user also",
  "tls_ca":     "/path/to/ca.pem, defaults to surveyor's ca if one exists",
  "tls_cert":   "/path/to/cert.pem, defaults to surveyor's cert if one exists",
  "tls_key":    "/path/to/key.pem, defaults to surveyor's key if one exists"
  }

With the values:

  jetstream:
    enabled: true
    accounts:
    - name: basic
      username: username
      password: password

This will output

# Source: surveyor/templates/configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: RELEASE-NAME-surveyor-accounts
  labels:
    helm.sh/chart: surveyor-0.16.0
    app.kubernetes.io/name: surveyor
    app.kubernetes.io/instance: RELEASE-NAME
    app.kubernetes.io/version: "0.5.0"
    app.kubernetes.io/managed-by: Helm
data:
  basic.json: |
    {"name":"basic","password":"password","username":"username"}

For context, I cannot use surveyor right now for the 2 fixes

Done. I changed it to 0.5.1 and I need another approval.
