Add hint about adding variables for Auto DevOps application variables
and link to More information

- DRY up setting deploy name

- DRY up application_secret_name

Use --from-env-file with bash process substitution

We still need bash as process substition (`<()`) is not available in sh

ie. fix below quoting issue:

```
kubectl create secret -n project-with-autodevops-900057eb1ce34399-77 \
  generic production-secret \
  '--from-literal=OPTIONAL_MESSAGE=You' can see this secret \
  -o yaml --dry-run
```

With fix, it should be generating:

```
kubectl create secret -n project-with-autodevops-900057eb1ce34399-77 \
  generic production-secret \
  --from-literal 'OPTIONAL_MESSAGE=You can see this secret' \
  -o yaml --dry-run
```

Call via bash -c, instead of assuming bash

The shell is /bin/sh, so we cannot asssume bash. Hence we use `bash -c`

bash is installed for deploy jobs in a prior step

Find any CI variables from `env` which has a prefix. If there are any
such CI variables, strip prefix from variable name then create a generic
Kubernetes secret containing all these CI variables as key-value pairs.

Also, Pass in secretname to application container

The secretname may be present, if nil, the chart does nothing. If
present, the chart will load the key-value pairs from the secret into
the application container. See
