c5a80cc488 Use env_secure_(alloc/free) macro for metadata allocations
Adapter can opt to take additional steps to securely allocate
memory used by OCF to store cache metadata. Typically this would
involve mlocking pages and zeroing memory before deallocation.

Memory allocated using secure_alloc is not expected to be zeroed
or physically continous.

e53944d472 Dynamic I/O queue management
- Queue allocation is now separated from starting cache.
- Queue can be created and destroyed in runtime.
- All queue ops accept queue handle instead of queue id.
- Cache stores queues as list instead of array.
