clone: do not let --depth imply --shallow-submodules

Browse Source 
In v2.9.0, we prematurely flipped the default to force cloning
submodules shallowly, when the superproject is getting cloned
shallowly.  This is likely to fail when the upstream repositories
submodules are cloned from a repository that is not prepared to
serve histories that ends at a commit that is not at the tip of a
branch, and we know the world is not yet ready.

Use a safer default to clone the submodules fully, unless the user
tells us that she knows that the upstream repository of the
submodules are willing to cooperate with "--shallow-submodules"
option.

Create a 'shallow' clone with a history truncated to the
specified number of revisions. Implies `--single-branch` unless
`--no-single-branch` is given to fetch the histories near the
tips of all branches. This implies `--shallow-submodules`. If
you want to have a shallow superproject clone, but full submodules,
