## Changes
Modified interpolation logic to use:
`\$\{([a-zA-Z]+([-_]*[a-zA-Z0-9]+)*(\.[a-zA-Z]+([-_]*[a-zA-Z0-9]+)*)*)\}`
**Edit**: Suggested by @pietern
`\$\{([a-zA-Z]+([-_]?[a-zA-Z0-9]+)*(\.[a-zA-Z]+([-_]?[a-zA-Z0-9]+)*)*)\}`
to be more selective and not allow consequent hyphens or underscores to
make the keys more readable.
Explanation:
1. All interpolation starts with `${` and ends with `}`
2. All interpolated locations are split by by `.`
3. All sections are expected to start with a alphabet `[a-zA-Z]`; no
numbers, hyphens or underscores.
4. All sections are expected to end with an alphanumeric `[a-zA-Z0-9]`
no hyphens or underscores
This change allows the current interpolation to be more permissive.
**Note** it does break backwards compatibility because `[a-zA-Z] !=
[\w]`. `\w` includes alphanumeric and underscores. `\w = [a-zA-Z0-9_]`
## Tests
There are two tests with examples of valid and invalid interpolation and
a test to validate expansion.
## Changes
Rename all instances of "bricks" to "databricks".
## Tests
* Confirmed the goreleaser build works, uses the correct new binary
name, and produces the right archives.
* Help output is confirmed to be correct.
* Output of `git grep -w bricks` is minimal with a couple changes
remaining for after the repository rename.
## Changes
This PR now allows you to define variables in the bundle config and set
them in three ways
1. command line args
2. process environment variable
3. in the bundle config itself
## Tests
manually, unit, and black box tests

## Changes
Traverses the variables referred in a depth first manner to resolve
string fields.
Errors out if a cycle is detected
## Tests
Manually and unit/blackbox tests
By specifying a function typed `LookupFunction` the caller can customize
which path expressions to interpolate and which ones to skip. When we
express dependencies between resources their values are known by
Terraform at deploy time. Therefore, we have to skip interpolation for
`${resources.jobs.my_job.id}` and instead rewrite it to
`${databricks_job.my_job.id}` before passing it along to Terraform.
Performs interpolation on string field.
It looks for patterns `${foo.bar}` where `foo.bar` points to a string
field in the configuration data model.
It does not support traversal (e.g. `${foo}` with `foo` equal
to`${bar}`), hence "rudimentary".
