Devfile: tools should be renamed components

[l0rd]

Description

Component is a better name. It's more generic and tools is ok for IDE tools (language suppport, debugging etc...) but less for IDE runtimes (application servers, databases etc....) or editors (e.g. theia).

And we need to do the renaming also to align with odo terminology

So a devfile would look like:

---
specVersion: 0.0.1
name: petclinic-dev-environment
projects:
     (...)
components:
     (...)
commands:
   - name: (...)
     actions:
       - type: exec
         component: mysql
         (...)

This is an incompatible change. That means that if we do that devfiles with "tools" would not work. We have "spec Version" to handle such a situation in the future. But at this time we have no code behind it to support incompatible changes. If we take in to account amount of other work "devfile" related work and the fact that we are in 7.x-beta it doesn't make sense to spend a lot of time on backward support before GA. So the plan:

• to do a change
• send a note to the mail list.
