Enrich rdmatool with an option to set network namespace of RDMA
device. After successful execution of it, rdma device will
be accessible only in assigned network namespace.
rdma tool command examples and output.
First set netns mode to exclusive.
$ rdma system set netns exclusive
Now create network namespace and assign RDMA device to this
network namespace.
$ ip netns add foo
$ rdma dev set mlx5_1 netns foo

There is a need to distinguish between driver vs. general exposed
attributes. The most common use case is to expose some internal
garbage under extremely common and sexy name, e.g. pi, ci e.t.c
In order to achieve that, we will add "drv_" prefix to all strings
which were received through RDMA_NLDEV_ATTR_DRIVER_* attributes.

Globally replace all filter function in safer variants of those

Such conversion allowed to fix a number of places in the code, where
the previous implementation didn't honor filter requests if netlink
