Fix for manage Hex String in SnmpMonitor
It is possible to set a new parameter hex to true
if you want to treat the string as an OctetString
in the SnmpMonitor configuration

This has been discussed and the solution is to add a parameter hex the hex value can be false|true.
Default hex parameter value is false. When hex is true then the content is declared as octetstring and not as a displaystring.
By default snmpMonitor class convert the string as a displayString.
If the hex="true" then it is converted using the toHexString() method of SnmpValue class.

In the case you want to check over and hex defined value from a specific oid you do not have any ability.
It would be useful to convert the hex value as a string and then match the corresponding sting using the ~ and = operator.
