Add Oracle as a vendor and OS Type

[agrare]

Add Oracle as a supported vendor and oracle linux as a supported OperatingSystem type

Required for:

• Add initial EmsRefresh for Oracle Cloud manageiq-providers-oracle_cloud#4

[agrare]

So we have a line-item for this in the pluggability checklist #19440 but since this is a rails validation I'm getting a cyclic dependency error when trying to load up leaf_subclasses

[Fryguy]

If you have a vendor image we should also add that to decorators for consistency: https://github.com/ManageIQ/manageiq-decorators/tree/master/app/assets/images/svg

[Fryguy]

oh actually it's already there - https://github.com/ManageIQ/manageiq-decorators/blob/master/app/assets/images/svg/vendor-oracle_cloud.svg

[agrare]

Well that's convenient 😄

[Fryguy]

Oh wait, I thought this was a vendor... (i.e. oracle cloud), as opposed to an OS (oracle linux). we don't have an image for oracle linux.

[Fryguy]

To clarify, this is Oracle Cloud.

[agrare]

👍 the vendor-oracle.svg is being picked up already

[Fryguy]

And this is Oracle Linux.

[agrare]

So we just need a os-linux_oracle icon

[Fryguy]

you can probably symlink like we do for other images.
