[PATCH v2 1/3] Make lnk home argument for gitd optional Export this patch

Make the lnk-home argument optional so that by default lnk-gitd uses
the `LnkHome::ProjectDirs`.

Doesn't need to be done now, but we should link this up with
`--verbose`/`--quiet` configurations.

+Here's how to get a simple lnk setup up and running on linux using systemd.
+
+## Build and install the CLI tools
+
+```
+cd bins
+cargo install --path lnk-gitd
+cargo install --path lnk
+```
+
+## Setup your local identity
+
+```
+# create a profile
+lnk profile create
+# create your person identity, record the `urn` field of the resulting JSON
+lnk identities person create --payload '{"name": "<your display name>"}'
+lnk identities local set --urn <the urn from above>
+```
+
+## Add your seeds
+
+Modify `$XDG_CONFIG_DIR/.radicle-link/<profile ID>/seeds`, add the following
+line:
+
+```
+<your seed peer ID>@<address>:<port>
+```
+
+Note that the active profile can be found with `lnk profile get`
+
+
+## Create the unit files
+
+Copy `example-systemd-config/lnk-gitd.service` to `$XDG_CONFIG_DIR/user`. Modify
+it so that the `<your lnk-gitd>` points at the location of the `lnk-gitd` you
+installed above (probably `$HOME/.cargo/bin/lnk-gitd`).
+
+Copy `example-systemd-config/lnk-gitd.socket` to `$XDG_CONFIG_DIR/user`, modify
+the port in `ListenStream` to be wherever you want the git server to run.
+
+Finally, enable the socket with `systemctl --user enable lnk-gitd.socket`
+
+
+## Clone a project and mess around and add remote config
+
+```
+lnk clone --urn <some project>
+cd <project name>
+```
+
+You'll need to update the project config to point `rad://` urls at `lnk-gitd`.
+Put the following lines in `.git/config`
+
+```
+[url "ssh://127.0.0.1:9987/rad:git:"]
+    insteadOf = "rad://"
+```
+
+Note that you can't currently put this in `~/.gitconfig` as it messes up `lnk
+clone`.
+
+
+## Off you go
+
+Now you can push and pull from your monorepo via `git push rad`. Currently you
+will need to add remotes for each other peer you want to work, this will be
+fixed once we have updated `lnk sync` to update include files.
