display cpu/memory utilization for containers / resources

[nicks]

Some users have asked for an easy way to see in the Tilt UI if one server is using way too much CPU or memory

Related to #3116, #3117, and some of the other performance degradation research we did. We ended up tabling this work but may come back to it.

Would love this out of the box too.

For a local dev setup, developers usually different machine specs ( in our case, M1's runs containers smoothly, but non-m1 struggle to run the exact same containers and struggle for passing the healthchecks probes. Ideally some stats could be shared exported to know what's happening.

An easy alternative to check the cluster is to use Lens (but not at the pods level unfortunately):

Some alternative existing solutions, but require additional work:

• run {prometheus locally
