Description

Jira Link: DB-19966

Description

Plan is to pass this flag with a value of true for instances running in YBM. That is, the code that starts these processes on YBM will set this flag to true.

Flag should default to false.

For now, nothing will be reading this flag. We plan to use this flag to roll out some features to YBM first and only later to YBA/OSS.

Probably want to put this in common_flags.h or the equivalent

(We need the flag defined first before YBM can start passing it.)

backport this to 2024.2, 2025.1, 2025.2

Research direction
Examine the pattern for defining gflags in common flags.h (likely in src/yb/common/common flags.h). Add a new gflag called 'is yb managed' with default false. Ensure it is accessible from both master and TServer processes. No code should read this flag yet; only define it. Consult existing gflag definitions for proper registration and declaration. The backporting to specific versions can be addressed after the initial implementation.
