Add validation for xnames in BootparametersPost and enhance tests

[alexlovelltroy]

This adds validation of xnames for bss using the Cray-HPE xname library and adds tests to validate the behavior I believe is requested in #51

Looks good. According to the OpenAPI spec, PUT only updates and does not create new so I think implementing the check just for POST is fine for now.

Unfortunately, it looks like there may have been premature optimization here as this field (according to the comment above) is supposed to support xnames and "special names" (i.e. groups). However, the current BSS does not support boot groups with Postgres (yet). This may change with a solution to #50. However for now, this is fine as-is.

See comment in pkg/bssTypes/types.go on line 61. When a solution comes for the mentioned issue, this may change to be conditional in the future.
