docs: Generates a property filter condition string for an <code>int</code> value. Creates a formatted string to use
  in a filter expression that uses the specified operation to compare the property with the value, formatted as
  a numeric value, as in the following example:
  <p>
  <code>String condition = generateFilterCondition("Population", QueryComparisons.GREATER_THAN, 1000);</code>
  <p>
  This statement sets <code>condition</code> to the following value:
  <p>
  <code>Population gt 1000</code>
  
  @param propertyName
  A <code>String</code> which specifies the name of the property to compare.
  @param operation
  A <code>String</code> which specifies the comparison operator to use.
  @param value
  An <code>int</code> which specifies the value to compare with the property.
  @return
  A <code>String</code> which represents the formatted filter condition.
