Currently, the default web-terminal-tooling image prepopulates a .bashrc file in $HOME with completions for some tooling. However, this means that if we want to enable a persistent home directory (by mounting a volume there), those files will be wiped out when kubernetes mounts a volume.

We should instead store a default .bashrc and any other files in another directory and copy them over to $HOME (if they do not already exist) on startup.
