[feat] Add new `sched_bind_options` environment configuration option for emitting environment-specific scheduler options

[ekouts]

Closes #2991.

I am a bit confused by a comment from @vkarak in the issue:

Just to be clear, the above syntax is proposed for the partition definition.

Why would these options be defined in the partition?

I was about to merge this, but read this and the original issue:

Why would these options be defined in the partition?

@ekouts Yes, it was proposed to be in the environs because it's a partition's property how you should bind the environment and not the environment's.

I'm removing it from 4.5 as we need to understand what's the best way to implement it.
