Export functionality to load Kubeconfig from text

[imp]

Would you like to work on this feature?

yes

What problem are you trying to solve?

Besides loading Kubeconfig from files or env var, there are situations where you have plain text coming from somewhere else, rather than a file. For example, when working with ClusterAPI the Kubeconfig is stored in the secret. It might be a good idea to provide an impl FromStr for Kubeconfig and let every other higher-level functions just use it.

Describe the solution you'd like

impl FromStr for Kubeconfig

Describe alternatives you've considered

An alternative would be to write just a free-standing function or just implement it (really two-liners) in your own code.

Documentation, Adoption, Migration Strategy

Well, the use should be straightforward, via parse() method

Target crate for feature

kube-client

Like this?

let config: Kubeconfig = serde_yaml::from_str(secret).unwrap();

I guess it makes sense to expose something that does what Kubeconfig::read_from does in the absense of a file path now that we handle multi-doc kubeconfigs. Plus it potentially allows users to not having to manually specify serde_yaml in their cargo toml if this is their only use case.

I'm 👍 . Happy to review a PR.
