New component: filestatsreceiver

[atoulme]

The purpose and use-cases of the new component

This receiver communicates metrics related to file information.

The component exposes the following metrics:

• file.size: size of the file or folder in bytes.
• file.mtime: last modification timestamp of the file, in seconds since Epoch.
• file.ctime: last modification or permission change timestamp of the file, in seconds since Epoch.
• file.atime: last access timestamp of the file, in seconds since Epoch.

Each metric will come with the following attributes:

* `file.path`: the absolute path to the file or folder

This receiver acts like a scraper, with a default collection interval of 30s. The receiver accepts the following configuration:

Field	Default	Description
include	required	A list of file glob patterns that match the file or folder paths to be scraped
exclude	[]	A list of file or folder glob patterns to exclude from scraping

In case of error with a specific file during scraping, the receiver will log a partial scraping error and continue to try on other files.

Example configuration for the component

  include: ["/etc/apache/sites-enabled/*"]
  exclude: ["/etc/apache/sites-enabled/README"]
  metrics:
    file.size:
      enabled: false
