Incorrect JSON output in `okteto deploy`

[maroshii]

Describe the bug okteto deploy -o json should send all output in json format. There are a few lines that are not in json which makes it hard to parse the output:

$ okteto deploy -o json
 i  Using maroshii @ cloud.okteto.com as context
{"level":"info","stage":"okteto build -t okteto.dev/api:${OKTETO_GIT_COMMIT} api","message":" i  Running your build in tcp://addr:1234...","timestamp":1639512885}
{"level":"info","stage":"okteto build -t okteto.dev/api:${OKTETO_GIT_COMMIT} api","message":"#2 [internal] load .dockerignore","timestamp":1639512886}
...
{"level":"info","stage":"helm upgrade --install catalog chart --set tag=${OKTETO_GIT_COMMIT}","message":"TEST SUITE: None","timestamp":1639513441}
 i  Endpoints available:
  - https://catalog-chart-maroshii...
  - https://catalog-chart-maroshii...

Expected behavior Either add a --silent option or send the output in json as the other lines with an empty stage (so it can be easily omitted on the other side)

This also happens for errors:

{"level":"info","stage":"helm upgrade --install movies chart --set tag=${OKTETO_GIT_COMMIT}","message":"Release \"movies\" does not exist. Installing it now.","timestamp":1639588299}
 x  Error executing command 'helm upgrade --install movies chart --set tag=${OKTETO_GIT_COMMIT}': exit status 1

Which doesn't allow correctly parsing error lines.

For errors we should probably set stage="error" or keep the previous stage if possible. For non important lines that are not part of a stage we can probably go with stage=""
