Hello,

I am configuring an ELK stack and would like to use filebeat to read in zeek logs. Below is a snippet of my filebeat module configuration:

```auto
# cat /etc/filebeat/modules.d/zeek.yml
- module: zeek
  capture_loss:
    enabled: true
    var.paths: ["/var/log/zeek/capture_loss.log"]
  connection:
    enabled: true
    var.paths: ["/var/log/zeek/conn.log"]
  dce_rpc:
    enabled: false
  dhcp:
    enabled: true
    var.paths: ["/var/log/zeek/dhcp.log"]
  dnp3:
    enabled: false
  dns:
    enabled: true
    var.paths: ["/var/log/zeek/dns.log"]
  dpd:
    enabled: false
  files:
    enabled: true
    var.paths: ["/var/log/zeek/files.log"]

```

I would like to add a tag to all the outputs from this module using an environment variable something along the lines of:

```auto
  input:
    processors:
      - add_tags:
          tags: ["${SOURCE}"]
          target: "pcapSource"

```

How would I go about configuring this?
