Add ignore and restrict options to localfile configuration

[chemamartinez]

Hi team,

As part of wazuh/wazuh#5628 new options have been added to the Logcollector configuration in order to be able to ignore and restrict specific log entries.

The added options are:

• ignore
• restrict

In the configuration they are defined as follows:

  <localfile>
    <log_format>json</log_format>
    <location>/testignore.log</location>
    <ignore type="pcre2">regex_value</ignore>
  </localfile>

  <localfile>
    <log_format>syslog</log_format>
    <location>/testrestrict.log</location>
    <restrict type="osregex">regex_value</restrict>
  </localfile>

Every tag includes a value and a type. Also, more than one tag can be added to the same localfile.

When requesting the active configuration, new options are defined as follows:

• For the following configuration:

  <localfile>
    <log_format>syslog</log_format>
    <location>/var/log/file.log</location>
    <ignore type="pcre2">value1</ignore>
    <ignore type="osmatch">vale2</ignore>
    <restrict type="osregex">value3</restrict>
  </localfile>

• API output:

                        "type": "osmatch"
                     }
                  ],
                  "restrict": [
                     {
                        "value": "value3",
                        "type": "osregex"
                     }
                  ]
               }
            ]
         }
      ],
