PMM-4879

Build: SUBMODULES-2465

• pmm
• pmm-admin
• pmm-agent

Build will fail because I cannot use forked version of api (pmm) as dependency in mod.go. To acomplish this, api needs be merged and version of pmm api should be bumped.

This pull request is alternative for #1068.

FB failed to run tests because i used forked pmm-managed repository:
Percona-Lab/pmm-submodules#2465
During pmm2-api-tests scripts tries to checkout branch on wrong repository (it should be the forked one):
https://pmm.cd.percona.com/blue/organizations/jenkins/pmm2-api-tests/detail/pmm2-api-tests/9910/pipeline

[pkadej]

Closing because PR from forked pmm-managed repository was merged instead of this one.
