The package defined various special errors; these errors existed for two reasons;
- being able to distinguish "not found" errors from other errors (as "not found"
errors can be ignored in various cases).
- to be able to update the context _name_ in the error message after the error
was created. This was needed in cases where the name was not available at the
location where the error was produced (e.g. only the "id" was present), and
the helpers to detect "not found" errors did not support wrapped errors (so
wrapping the error with a "name" could break logic); a `setContextName` interface
and corresponding `patchErrContextName()` utility was created for this (which
was a "creative", but not very standard approach).
This patch:
- Removes the special error-types, replacing them with errdefs definitions (which
is a more common approach in our code-base to detect error types / classes).
- Removes the internal utilities for error-handling, and deprecates the exported
utilities (to allow external consumers to adjust their code).
- Some errors have been enriched with detailed information (which may be useful
for debugging / problem solving).
- Note that in some cases, `patchErrContextName()` was called, but the code
producing the error would never return a `setContextName` error, so would
never update the error message.

Avoid updating the config-file if nothing changed. This also prevents creating
the file and config-directory if the default is used and no config-file existed
yet.
`config.Save()` performs various steps (creating the directory, updating
or copying permissions, etc etc), which are not needed if the defaults are
used; a445d97c25/cli/config/configfile/file.go (L135-L176)

This will allow plugins to have custom typed endpoints, as well as
create/remove/update contexts with the exact same results as the main
CLI (thinking of things like `docker ee login https://my-ucp-server
--context ucp-prod)`
