FIM tab rework

[jesusgn90]

Hi team,

The tab Agent > FIM needs changes, here are some proposals:

• State interface (now it's "Show files"), should be shown by default.
• Expand the default number of rows for the files table to 100.
• Add SHA1 and MD5 hashes to the table.
• Show a new table with the configuration for that agent (directories, realtime, who-data, report changes, ignores, restricts...)
• Add a chart for showing the number of files by owner/group/permissions.
• Add a chart for showing the number of files by monitored directories.
• If we click on a file, it should show some stats such as the number of alerts for that file or the option to filter alerts by that file.
