Do we care about import order, alphabetically or something?

The hooks run regardless of the result, and are not aware of the result. Perhaps worth passing it to them?

- Post hook won't run if 'func' throws an exception, do we want to change this behavior ?
- When passing 'result' to the post hook I need to assume that it is a string, or can be evaluated to a meaningful string, I'm not sure that I can take this assumption.

I want to preserve the order in which the hooks were mentioned in the init file, but now I realize that I didn't prefix them with an index. will fix.

Some possible use-cases of VM hooks:
Some possible use-cases of Host hooks:
|
1. The hooks are defined in the init file and can be any type of script (shell, python...). 2. The hooks will be run on the host which runs Lago. 3. Hooks will be only supported for functions that were decorated with "hooks.with_hooks" (for now just start / stop) Signed-off-by: gbenhaim <[email protected]>
