context deadline exceeded with a large git repository

[nobuto-m]

Bug Description

When I tried to use https://github.com/ceph/ceph.git, the git repository wouldn't be available in the filesystem somehow.

Once looking at the detail, it hit into:

too many failures, aborting" "error"="Run(git submodule update --init --recursive --depth 1): context deadline exceeded:

Two suggestions here:

1. support specifying git submodule behavior in the charm configuration to minimize the data to download

/git-sync --help
...
-submodules string
   git submodule behavior: one of 'recursive', 'shallow', or 'off' (default "recursive")

2. support customizing the deadline

To Reproduce

juju deploy -m cos cos-configuration-k8s cos-configuration \
    --config git_repo=https://github.com/ceph/ceph.git \
    --config git_branch=main \
    --config grafana_dashboards_path=monitoring/ceph-mixin/dashboards_out/

Environment

# /git-sync --version
v3.5.0

# git version
git version 2.30.2

cos-configuration 3.5.0 cos-configuration-k8s  latest/edge   39

Relevant log output

# /git-sync --repo https://github.com/ceph/ceph.git --branch main --rev HEAD --depth 1 --root /git --dest repo --one-time -v 1
