## Changes
Move the WorkspaceClient reader and setter from the root package to
`libs/command`.
## Why
This allows us to read the workspace client set in the context in all
CLI packages. This was not possible before because using
`root.WorkspaceClient` would often result in an import cycle.
This would also allow us to standardise reads of the workspace client to
be from the context in bundle commands. Today those are read from the
bundle object tree instead.
This is a natural followup to
https://github.com/databricks/cli/pull/2440.
## Tests
Existing tests and one new unit test.
NO_CHANGELOG=true
## Changes
Added JSON input validation for CLI commands. Now when invalid JSON
passed as a payload to CLI commands, CLI performs input normalisation
and detects if there are any mismatches such as incorrect types, unknown
fields and etc.
This diagnostic information is printed in standard error output and does
not block command execution, so the change is backward compatible.
Fixes#1769#1764#1625#1560
## Tests
Added unit tests
