## Changes
Some diagnostics can have multiple paths associated with them. For
instance, ensuring that unique resource keys are used across all
resources. This PR extends `diag.Diagnostic` to accept multiple paths.
This PR is symmetrical to
https://github.com/databricks/cli/pull/1610/files
## Tests
Unit tests
## Changes
This PR changes `diag.Diagnostics` to allow including multiple locations
associated with the diagnostic message. The diagnostics that now return
multiple locations with this PR are:
1. Warning for unknown keys in config.
2. Use of experimental.run_as
3. Accidental sync.exludes that exclude all files.
## Tests
Existing unit tests pass. New unit test case to assert on error message
when multiple locations are included.
Example output:
```
➜ bundle-playground-2 ~/cli2/cli/cli bundle validate
Warning: You are using the legacy mode of run_as. The support for this mode is experimental and might be removed in a future release of the CLI. In order to run the DLT pipelines in your DAB as the run_as user this mode changes the owners of the pipelines to the run_as identity, which requires the user deploying the bundle to be a workspace admin, and also a Metastore admin if the pipeline target is in UC.

## Changes
Print diagnostics in 'bundle deploy' similar to 'bundle validate'. This
way if a bundle has any errors or warnings, they are going to be easy to
notice.
NB: due to how we render errors, there is one extra trailing new line in
output, preserved in examples below
## Example: No errors or warnings
```
% databricks bundle deploy
Building default...
Deploying resources...
Updating deployment state...
Deployment complete!
```
## Example: Error on load
```
% databricks bundle deploy
Error: Databricks CLI version constraint not satisfied. Required: >= 1337.0.0, current: 0.0.0-dev
```
## Example: Warning on load
```
% databricks bundle deploy
Building default...
Deploying resources...
Updating deployment state...
Deployment complete!
Warning: unknown field: foo
in databricks.yml:6:1
```
## Example: Error + warning on load
```
% databricks bundle deploy
Warning: unknown field: foo
in databricks.yml:6:1
Error: something went wrong
```
## Example: Warning on load + error in init
```
% databricks bundle deploy
Warning: unknown field: foo
in databricks.yml:6:1
Error: Failed to xxx
in yyy.yml

## Tests
Tested manually
## Changes
This combination of changes allows pretty-printing errors happening
during the "load" and "init" phases, including their locations.
Move to render code into a separate module dedicated to rendering
`diag.Diagnostics` in a human-readable format. This will be used for the
`bundle deploy` command.
Preserve the "bundle" value if an error occurs in mutators. Rewrite the
go templates to handle the case when the bundle isn't yet loaded if an
error occurs during loading, that is possible now.
Improve rendering for errors and warnings:
- don't render empty locations
- render "details" for errors if they exist
Add `root.ErrAlreadyPrinted` indicating that the error was already
printed, and the CLI entry point shouldn't print it again.
## Tests
Add tests for output, that are especially handy to detect extra newlines
