* functions: add bounded concurrency
* functions: plug runners to sync and async interfaces
* functions: update documentation about the new env var
* functions: fix test flakiness
* functions: the runner is self-regulated, no need to set a number of runners
* functions: push the execution to the background on incoming requests
* functions: ensure async tasks are always on
* functions: add prioritization to tasks consumption
Ensure that Sync tasks are consumed before Async tasks. Also, fixes
termination races problems for free.
* functions: remove stale comments
* functions: improve mem availability calculation

- remove unnecessary goroutines
- fix stale docs
- reorganize import group
* Revert "functions: implement memory check for async runners using Cond vars"
This reverts commit 922e64032201a177c03ce6a46240925e3d35430d.
* Revert "functions: comment about rnr.hasAvailableMemory and sync.Cond"
This reverts commit 49ad7d52d341f12da9603b1a1df9d145871f0e0a.
* functions: set a minimum memory availability for sync
* functions: simplify the implementation by removing the priority queue
* functions: code grooming
- code deduplication
- review waitgroups Waits
* Reduce test verbosity
* Divert gin's log to the test buffer
* Divert stdlib's log to the test buffer
* Add bolt tests into log buffer
* Add a linebreak to improve log output layout
