rundeck option cannot take integer value

• Issue Type: Bug/Feature/Improvement/Documentation (pick one)
• Rundeck version: (enter version here)

Issue:

The following option definition in a simple rundeck jobdef:

    <option required="true" name="port" enforcedvalues="true" values="3800" value="3800">
      <description>username for the target database</description>
    </option>

does not work. To work around this problem, I had to place a non numeric character somewhere in the value for the values/value attributes. In this case, I simply placed a whitespace character in front of the integer:

    <option required="true" name="port" enforcedvalues="true" values=" 3800" value=" 3800">
      <description>username for the target database</description>
    </option>

Reproduce: (Enter steps to reproduce bug here.)

Define any job with above option that contains a pure integer value.

The output will result in:
