This pull request allows coder workspace agents to be reinitialized when a prebuilt workspace is claimed by a user. This facilitates the transfer of ownership between the anonymous prebuilds system user and the new owner of the workspace. Only a single agent per prebuilt workspace is supported for now, but plumbing has already been done to facilitate the seamless transition to multi-agent support. --------- Signed-off-by: Danny Kopping <dannykopping@gmail.com> Co-authored-by: Danny Kopping <dannykopping@gmail.com>
