Add better default suricata configuration for different traffic sizes and cpu/system architectures

Description
Related to improving Out of the Box Experience.
Often enough users struggle with coming up with a decent 1Gbps suricata.yaml config for example. It will be useful in terms of user experience to ship/install Suricata with some recommendations/examples for the following scenarios:
- 1 Gpbs
- 10 Gbps
- 2-3 (sniffing) port
- IPS set up for AFP
etc..
The above should be based on certain assumptions (mainly available CPU/RAM etc).
- Assignee set to OISF Dev
- Target version set to TBD
I think this ticket contains 2 separate tasks: 1) create an easy system to produce these configs based on a single 'master' yaml. 2) define the various settings for the various profiles.
Would you then ship different suricata.yaml files or is it just a documentation thingy?
The idea is to ship multiple yamls for those different performance profiles.
A few thoughts here.
We should identify all the fields in the suricata.yaml that would need to be customized and put place_holder type values in them. Then using YAML, we could create a file with a list of named profiles to provide these values. A Python script (or even sed) could output a config with the place_holder values replaced. Idea for profiles could be AWS instance types, or suggested settings for certain requirements.
Would it make sense for a script to profile the system (memory size, etc) and auto-generate a profile?
Script could be part of suricatactl.
A script would make sense indeed - though the expectation would be that Suri only would be running on the system.
Long time ago I started this - https://github.com/pevma/AAIS as part of similar effort.
We could also set up couple of "hardcoded" configs that aim at covering 1Gbps setups - those should be pretty easy I think. A 10Gbps setup would be a bit more complex as it would depend actually also on NUMA/Intel/AMD architecture.
