Native driver bugfixes and org improvements

[sparshev]

Fixed multiple issues with Native driver on macos - mostly:

• Proper passing of metadata as env variables to the workload - sudo & su are quite prohibitive there and to not make the node config harder I used just storing the metadata to env export variable and source it in the shell command. The file is stored in tmp and available via ACL to the newly created user only.
• Proper log output for the workload right into the node log - it prepends stdout/stderr lines with the resource identifier and looks nice.
• Using current fish node group as dynamic user group by default - otherwise the user is incomplete.
• Configuration for the binaries location - by default it tries to find it in PATH, but now it's easy to override.

Also a couple of small improvements:

• Moved improved tests helpers from AF-30 Clustering implementation #54
• Moved a couple of fixes for build system from AF-30 Clustering implementation #54

Fixes: #2

Motivation and Context

m1 mac machines is here and it's good to have dynamic envs on them and VMX is much harder to prepare for m1 properly, so native driver could be a good replacement, as well as it should help with VMX images building as well.

Found that on M1 it doesn't want to allow to delete user via dscl even with proper sudoers rules:

Command exited with error: exit status 40: <main> delete status: eDSPermissionError <dscl_cmd> DS Error: -14120 (eDSPermissionError)

So after installation aquarium-fish binary should be added to TCC database /Library/Application Support/com.apple.TCC/TCC.db to allow kTCCServiceSystemPolicySysAdminFiles or kTCCServiceSystemPolicyAllFiles. Also it could be done through Privacy & Security in MacOS preferences after aquarium-fish started and failed with verification of native driver.
