For some reason the API server may want to pass an already mutated CR
through the webhook once again. The webhook must accept such CR with
no additional transformations.
This patch adds support for such idempotence by maintaining
a set of identity mappings which effectively resolve to themselves. No
patching is applied to them.
Fixes a linter warning:
"unexported-return: exported method GetPatcher returns unexported type
*patcher.patcher, which can be annoying to use (revive)"

Webhook's patcher currently can't be re-applied to its output because it
rejects containers with the env vars it adds (e.i. FPGA_AFU_* and
FPGA_REGION_*).
Instead of rejecting container with disallowed env vars just reset them
first upon patching.
Add govet-fieldalignment to .golangci.yml
Fix errors that come from adding govet-fieldalignment
- by reordering the fields of structs
- by putting nolint:govet annotations

The function will be re-used by other webhooks too so it's better
to move it to its own package.
The unit tests are taken from the original implementation with some
minor changes.

This commit adds new function validateContainer() that runs the
same FPGA_* ENV validation checks as before in getRequestedResources().
The restructuring is done in preparations for moving
getRequestedResources() to a separate package.
