Customize emails for guest password SMS

Log in to the Abiquo API Server as an administrator
In the config folder, if there is no mail folder, create a mail folder and set the owner as the tomcat user
```
/opt/abiquo/config/mail
```
In the mail folder, create the following files
1. Email file
  guestPasswordSMSTemplate_en_US.mustache
```
Virtual machine:
Uuid: {{vmuuid}} Name: {{vmname}} ProviderId: {{vmproviderid}}
Password:
{{loginpassword}}
```
2. The additional content that you can add for this SMS is as follows
```
Login user:
{{loginuser}}
Fully qualified domain name:
{{fqdn}}
User that created the VM:
{{username}}
```
3. Properties file
  guestPasswordSMS_en_US.properties
```
-
```
  1. By default the properties file is empty for the guest password SMS message
Optionally add custom variables and content
1. In the email body, to add a custom variable, use double curly braces (also called double mustaches). For example
```
<p>Please call your system Administrator on <strong>{{helpline}}</strong></p>
```
2. Then in your properties file, set value for your custom variable
```
helpline=555 12345
```
  To return unescaped HTML as part of a template property, use the triple mustache, which is "{{{" and "}}}".
  The Mustache templating software that adds the property values will escape HTML variables in double mustaches by default.
If your users have a language other than English, rename the file to change the language code to the user language
1. For example, for "Spanish - Spain" change the en_US to es_ES
2. The user language is the UI language when you create the user
Change the owner of the files to the tomcat user
