* Parse --affinity options for validity to `ctx.affinities`.

* Later (in `resolveLocality`) we'll translate this to locality hints

|
|
*
|

|

|
|

|
|
* inst==~vm1 # '~' for soft/non-strict
|
|
* inst!=~vm1

|
|
* inst!=/vm\d/ # regex (not yet supported)
|
|

|
|
* some-tag!=db # tags (not yet supported)
|
|
*
|
|
* Limitations:
|
|
* - no support for tags yet
|
|
* - no globbing or regex yet
|
|
* - we resolve name -> instance id *client-side* for now (until
|
|
* CloudAPI supports that)
|
|
* - Triton doesn't support mixed strict and non-strict, so we error
|
|
* out on that. We *could* just drop the non-strict, but that is
|
|
* slightly different.
