Updates for MRC/Morpheus to build in the same RAPIDS devcontainer environment

[cwharris]

Adds a new dependencies.yaml which is used in RAPIDS devcontainer utils to generate conda env yamls, project.toml's, and setup.pys on-the-fly using https://github.com/rapidsai/dependency-file-generator. Eventually we can generate/verify our existing environment files this way, but for now this gets us up and running in a RAPIDS devcontainer.

Also fixes an issue where newer versions of Boost provide an overload to http request header insert where our existing usage would be ambiguous.

MRC/Morpheus unified build environment is a WIP, but available here: https://github.com/cwharris/cyber-dev.

Depends on nv-morpheus/utilities#55

Contributes to #704
