AIX platform needs a note indicating that logrotate should be installed manually

[cwjohnston]

This is an issue with:

• Bug (site functionality or styling)
• Errata (fix needed for doc content)
• New content (guide wanted)

Expected Behavior

Sensu service logs should be automatically rotated via logrotate on all supported platforms.

Current Behavior

Sensu service logs are automatically rotated on Linux and Windows platforms, possibly others, but AIX does not provide logrotate by default and the AIX package does not indicate logrotate as a dependency.

Possible Solution

Because we don't want to add a hard dependency on logrotate to the AIX package, we should add a note on the AIX platform page indicating that logrotate should be installed to avoid filling the disk.

Context

See sensu/sensu#1864

• OS: AIX
