[JENKINS-23935] Allow tags for all instances in an EC2 cloud configuration

For cost and instance management it would be extremely useful to be able to configure a set of tags that apply to all instances.

Right now, if you want to add, say, a BillingCategory tag, you have to add it to each individual instance type. With lots of instance types that adds up.

Time permitting I'll have a go at implementing this, I just wanted to put the idea out there.

Start by locating the EC2 cloud configuration and the existing per-instance tag handling in the plugin. Trace how instance types are configured and provisioned, then determine how a shared tag set can be configured and applied to every instance; done means one common configuration covers all instance types without repeating the tags.
