These partial schemas are reused to build multiple request schemas

- PE_BOLTLIB_PATH =
PE_BOLTLIB_PATH is intended to function exactly like the BOLTLIB_PATH used in Bolt::PAL. Paths and variable names are similar to what exists in Bolt::PAL, but with a ‘PE’ prefix.

- DEFAULT_BOLT_CODEDIR =
For now at least, we maintain an entirely separate codedir from puppetserver by default, so that filesync can work properly. If filesync is not used, this can instead match the usual puppetserver codedir. See the ‘orchestrator.bolt.codedir` tk config setting.

Turns a Bolt::ResultSet object into a status hash that is fit to return to the client in a response.
If the ‘result_set` has more than one result, the status hash will have a `status` value and a list of target `results`. If the `result_set` contains only one item, it will be returned as a single result object. Set `aggregate` to treat it as a set of results with length 1 instead.

This function is nearly identical to Bolt::Pal’s ‘with_puppet_settings` with the one difference that we set the codedir to point to actual code, rather than the tmpdir. We only use this funtion inside the Modulepath initializer so that Puppet is correctly configured to pull environment configuration correctly. If we don’t set codedir in this way: when we try to load and interpolate the modulepath it won’t correctly load.
