Rename custom scripts for `plugin-add` and `plugin-remove` phases in plugins to make clear when they are executed:
`plugin-add` -> `post-plugin-add`
`plugin-remove` -> `pre-plugin-remove`
If asdf-vm was installed with a package manager and the user doesn't
have the necessary permissions to update it with `asdf update`, asdf-vm
emits an informational message and exits with exit code 1.
This makes it hard to programmatically detect whether the update failed
or wasn't even attempted because it's not possible.
With this change, asdf-vm would exit with the exit code 42 if updates are
disabled instead of exit code 1, which signals an error during update.

Previously, the shims directory was only excluded for system versions,
which meant that `asdf exec` would fall back to a shim if the install
didn't have the desired binary. If the shims are up to date this isn't a
problem since we check the metadata, but it causes issues if those are
out of sync for whatever reason.
I've checked all the uses of this function and I'm not seeing anywhere
we should need the old behavior.
It's possible for plugins to define new asdf commands. This way plugins can extend asdf capabilities or expose utilities related to their managed tool.
For example, a `foo` plugin might expose the command `asdf foo bar` by providing an executable file at `bin/bar`.
If `bin/bar` is a file but has no executable bit set, then its considered a source-able bash script, and will be sourced
with all the functions in `$ASDF_DIR/lib/utils.sh` already loaded.
A good example of this feature is the `nodejs` plugin, where people must import the release team keyring before
installing a nodejs version. People can execute the following command without having to know where exactly is the plugin located.
- remove test for install command edge case from parsing tool-versions (no longer relevant)
- add test for install command honoring legacy version files
- clean up test names to differentiate between installing a single version vs all dependencies
