# Description

<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->

This adds a new type `tokens.StackName` which is a relatively strongly
typed container for a stack name. The only weakly typed aspect of it is
Go will always allow the "zero" value to be created for a struct, which
for a stack name is the empty string which is invalid. To prevent
introducing unexpected empty strings when working with stack names the
`String()` method will panic for zero initialized stack names.
 
Apart from the zero value, all other instances of `StackName` are via
`ParseStackName` which returns a descriptive error if the string is not
valid.

This PR only updates "pkg/" to use this type. There are a number of
places in "sdk/" which could do with this type as well, but there's no
harm in doing a staggered roll out, and some parts of "sdk/" are user
facing and will probably have to stay on the current `tokens.Name` and
`tokens.QName` types.

There are two places in the system where we panic on invalid stack
names, both in the http backend. This _should_ be fine as we've had long
standing validation that stacks created in the service are valid stack
names.

Just in case people have managed to introduce invalid stack names, there
is the `PULUMI_DISABLE_VALIDATION` environment variable which will turn
off the validation _and_ panicing for stack names. Users can use that to
temporarily disable the validation and continue working, but it should
only be seen as a temporary measure. If they have invalid names they
should rename them, or if they think they should be valid raise an issue
with us to change the validation code.

If the change(s) in this PR is a modification of an existing call to the
Pulumi Cloud,
then the service should honor older versions of the CLI where this
change would not exist.
You must then bump the API version in

it to the service.
