[feat] execute a command synchronously

[adminy]

Describe the problem

In nodejs a lot of num modules use execSync or spawnSync. Some of these libs need complete re architecture just because there is no synchronous executor.

Would be nice to have it.

Describe the solution you'd like

Synchronous executor / command handler without async await.
