/**
 * Poll a table or oids from SNMP and build an RRD based on an array of arguments.
 *
 * Current limitations:
 *  - single MIB and RRD file for all graphs
 *  - single table per MIB
 *  - if set definition 'call_function', than poll used specific function for snmp walk/get,
 *    else by default used snmpwalk_cache_oid()
 *  - allowed oids only with simple numeric index (oid.0, oid.33), NOT allowed (oid.1.2.23)
 *  - only numeric data
 *
 * Example of (full) args array:
 *  array(
 *   'file'          => 'someTable.rrd',              // [MANDATORY] RRD filename, but if not set used MIB_table.rrd as filename
 *   'call_function' => 'snmpwalk_cache_oid'          // [OPTIONAL] Which function to use for snmp poll, bu default snmpwalk_cache_oid()
 *   'mib'           => 'SOMETHING-MIB',              // [OPTIONAL] MIB or list of MIBs separated by a colon
 *   'mib_dir'       => 'something',                  // [OPTIONAL] OS MIB directory or array of directories
 *   'graphs'        => array('one','two'),           // [OPTIONAL] List of graph_types that this table provides
 *   'table'         => 'someTable',                  // [RECOMENDED] Table name for OIDs
 *   'numeric'       => '.1.3.6.1.4.1.555.4.1.1.48',  // [OPTIONAL] Numeric table OID
 *   'ds_rename'     => array('http' => ''),          // [OPTIONAL] Array for renaming OIDs to DSes
 *   'oids'          => array(                        // List of OIDs you can use as key: full OID name
 *     'someOid' => array(                                 // OID name (You can use OID name, like 'cpvIKECurrSAs')
 *       'descr'     => 'Current IKE SAs',                 // [OPTIONAL] Description of the OID contents
 *       'numeric'   => '.1.3.6.1.4.1.555.4.1.1.48.45',    // [OPTIONAL] Numeric OID
 *       'index'     => '0',                               // [OPTIONAL] OID index, if not set equals '0'
 *       'ds_name'   => 'IKECurrSAs',                      // [OPTIONAL] DS name, if not set used OID name truncated to 19 chars
 *       'ds_type'   => 'GAUGE',                           // [OPTIONAL] DS type, if not set equals 'COUNTER'
 *       'ds_min'    => '0',                               // [OPTIONAL] Min value for DS, if not set equals 'U'
 *       'ds_max'    => '30000'                            // [OPTIONAL] Max value for DS, if not set equals '100000000000'
