[Bug]: Tolerations have no validation

[andrewballantyne]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Tolerations field in the Cluster Settings page for an Admin do not protect against any misuse of the field.

There are restrictions to the field under the hood, like having a valid K8s name (https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names) that we can do to help the admin out.

Tracking the valid relationship of the toleration is out of scope.

Expected Behavior

Present the user with additional error help when they have an invalid name.

"name part must consist of alphanumeric characters, '-', '' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9]')"

Steps To Reproduce

1. Be an admin
2. Go to Cluster Settings page
3. Type an invalid name with spaces or non-supported special characters

If part of this work we can do a wider box to at least support the default value would be awesome.
