ref(dependencies): Adding ability to install nested dependencies

[IanWoodard]

Fixes #65. Enables devservices to install recursive dependencies safely. It uses temp files and locks to avoid file contention and race conditions which occur when trying to install the same dependency multiple times at once. This actually happens quite often since both Relay and Snuba depend on Kafka, meaning there is a decent chance they will both try to install Kafka at similar times and likely run into a race condition if it weren't for the safeguards added. This change's locking behavior is a bit naive and could be further improved to simply avoid installing dependencies that have been or are currently installing, but as a first iteration, this gets the job done in a safe and robust way. Additionally, I opted to utilize the ~/.cache directory for storing the dependencies rather than the ~/.local/share.
