cbdcef097f Fix race condition in tests
All checks were successful
continuous-integration/drone/push Build is passing
Details 
In normal usage, the io.Writer passed to the watcher is typically
`os.Stdout` and does not require locking because it is not being read
from inside the same process.

In tests however, the io.Writer was a *bytes.Buffer which is read
concurrently from another goroutine, introducing a race condition. This
fixes the issue in the test suite by introducing a wrapper around
*bytes.Buffer which implements the required locking.

41f53c88df podWatcher: prefer bufio.Reader to Scanner
Some checks failed
continuous-integration/drone/push Build is failing
Details 
This avoids "token too large" errors when scanning large lines, probably
at the cost of some memory usage and/or allocations.
