Consolidate timeouts for `linkerd check`
- Moved the creation of contexts from inside the methods targeted by the
checks into a single place in the runCheck() and runCheckRPC() methods
where the context is built using a hard-coded timeout of 30 seconds.
- k8s' client-go doesn't allow passing along contexts, but it let's us
setting the Timeout manually.
- Reworded the description for the --wait option.

Version checks were not validating that the cli version matched the
control plane or data plane versions.
Add checks via the `linkerd check` command to validate the cli is
running the same version as the control and data plane.
Also add types around `channel-version` string parsing and matching. A
consequence being that during development `version.Version` changes from
`undefined` to `dev-undefined`.
