Add missing lib script to sentry-admin.sh

[djakielski]

Sentry Admin Script always fail because of missing import of lib script.

Fixes #3700.

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Heya, thanks for the PR! That said I don't think _lib.sh is needed in this script. I haven't seen anything referring to that and we actually test the backup and restore functionality using this script.

Can you share what kind of an error you are encountering for us to understand this better?

[djakielski]

Hey @BYK i got Issues that function vergte is unknow when ever I execute sentry-admin.sh no matter which parameter i add. After debugging I found that install/dc-detect-version.sh need this function. After fixing this locally, the script runs normaly.

[BYK]

Ah, right sorry! Yeah, since that vergte call is in a conditional I guess we never hit it in CI. Thanks so much for the patch and explanation again!

[aminvakil]

What do you say about moving vergte function to another file and only including that?

I'm seeing this in _lib.sh and I don't think it's appropriate to be executed at running sentry-admin.

log_file=sentry_install_log-$(date +'%Y-%m-%d_%H-%M-%S').txt
exec &> >(tee -a "$log_file")

There may be another problems as well.

[BYK]

@aminvakil yeah that makes total sense and probably explains the failure.

I'll give this a go today
