## Changes
This PR makes a few methods private, exposing cleaner interfaces to get
the string representations for enums and default values of a JSON
Schema.
## Tests
Manually, template initialization for the `default-python` template
still works as expected.
## Changes
Updates to bundle templates can require updated versions of the CLI.
This PR extends the JSON schema representation to allow template authors
to set a min CLI version they require for their templates.
This is required to make improvements/additions to the mlops-stacks repo
## Tests
Tested using unit tests and manually.
For manualy testing, I created a custom build of the CLI using go
releaser and then tested it against a local instance of mlops-stack
When mlops-stack schema has:
```
"min_databricks_cli_version": "v5000.1.1",
```
output (error as expected)
```
shreyas.goenka@THW32HFW6T bricks % ./dist/cli_darwin_arm64/databricks bundle init ~/mlops-stack
Error: minimum CLI version "v5000.1.1" is greater than current CLI version "v0.207.2-dev+1b992c0". Please upgrade your current Databricks CLI
```
When the mlops-stack schema has:
```
"min_databricks_cli_version": "v0.1.1",
```
output (validation passes)
```
shreyas.goenka@THW32HFW6T bricks % ./dist/cli_darwin_arm64/databricks bundle init ~/mlops-stack

## Changes
This PR introduces support for regex pattern validation in our custom
jsonschema validator. This allows us to fail early if a user enters an
invalid value for a field.
For example, now this is what initializing the default template looks
like with an invalid project name:
```
shreyas.goenka@THW32HFW6T bricks % cli bundle init
Template to use [default-python]:
Unique name for this project [my_project]: (_*_)
Error: invalid value for project_name: (_*_). Must consist of letter and underscores only.
```
## Tests
New unit tests and manually.
## Changes
This PR includes:
1. Adding enum field to the json schema struct
2. Adding prompting logic for enum values. See demo for how it looks
3. Validation rules, validating the default value and config values when
an enum list is specified
This will now enable template authors to use enums for input parameters.
## Tests
Manually and new unit tests
## Changes
At a high level this PR adds new schema validation and moves
functionality that should be present in the jsonschema package, but
resides in the template package today, to the jsonschema package. This
includes for example schema validation, schema instance validation, to /
from string conversion methods etc.
The list below outlines all the pieces that have been moved over, and
the new validation bits added.
This PR:
1. Adds casting default value of schema properties to integers to the
jsonschema.Load method.
2. Adds validation for default value types for schema properties,
checking they are consistant with the type defined.
3. Introduces the LoadInstance and ValidateInstance methods to the json
schema package. These methods can be used to read and validate JSON
documents against the schema.
4. Replaces validation done for template inputs to use the newly defined
JSON schema validation functions.
5. Moves to/from string and isInteger utility methods to the json schema
package.
## Tests
Existing and new unit tests.
## Changes
JSON schema properties are a map and thus unordered.
This PR introduces a JSON schema extension field called `order` to allow
template authors to define the order in which template variables should
be resolved/prompted.
## Tests
Unit tests.

## Changes
Adds a function to validate json schema types added by the author. The
default json unmarshaller does not validate that the parsed type matches
the enum defined in `jsonschema.Type`
Includes some other improvements to provide better error messages.
This PR was prompted by usability difficulties reported by @mingyu89
during mlops stack migration.
## Tests
Unit tests
## Changes
This PR:
1. Adds code for reading template configs and validating them against a
JSON schema.
2. Moves the json schema struct in `bundle/schema` to a separate library
package. This struct is now reused for validating template configs.
## Tests
Unit tests
