* feat: Decide upstream based on user's unix group membership
If a username is not defined, groupname is parsed. Check if the
user is part of that group and route them to the associated host
defined in the config file for the yaml plugin
* style: fix formatting with gofmt
* feat: Look up user groups only when groupname defined in yaml config
* fix: inefficient assignment because of unused var
* feat: fallback to next rule on group lookup failure
Instead of failing on group lookup errors, the matcher now skips the
groupname rule and proceeds to the next, eventually failing through to
the catchall rule.
* feat: test cases for group based routing in yaml plugin
* Revert "feat: fallback to next rule on group lookup failure"
This reverts commit 622ee9f1eb3157d04f57c068179bb74de8db3a1f.
Handles the error returned by getUserGroups instead of ignoring it,
to prevent potential runtime issues when user lookup fail
* feat: Check if a user is known to the system before group lookup
This will let the rule matching logic skip to the next pipe in the yaml
config when a user is not found on the system.
Note the variable name change from user to username to avoid ambiguity
dur to name collision with os/user package.

This commit adds a new test case to cover the scenario where multiple key files are used for authentication with the publickey_simple user. It generates a temporary key file and attempts to SSH to the piper server using both the correct and incorrect key files. The test verifies that the correct key file allows the connection and writes a random text to a shared file.
