allow integration management via hiera

[alaunay]

Hello,

This patch allows the configuration of integration of external tools (mattermost, slack, etc) using hiera.

Previously, there was a hook
define wazuh::integration()

which wasn't in use anywhere.

We stumbled across the same issue today. I found your merge request and adapted your changes. Everything works perfectly. Thanks

@alaunay Thanks for the contribution.
From trying your change we notices that so far (only) one integration seams to supported via hiera.
As Wazuh can handle multiple integration configurations, a support for multiple integrations would also be valuable to consider.

@AiaiM As it was originally your code, would you have a look at how supporting multiple integ ?

Hello @jzelina,
@AiaiM modified the code to support multi-integration, can you check if it fits your needs ?

Thanks for your contribution. I found one minor mistake. You renamed the template file to _integrations_epp. The file reference in the params_manager.pp still points to the old file. It should be:

$ossec_integration_template = 'wazuh/fragments/_integration.epp'

Hello @frittenlab,
I have fixed the file path in the params_manager.pp.

Hello, we did try the integration and it did work with multiple targets.
