Grow feature for IMSM metadata is currently fully supported and tested.
Reshape operation is not in experimental state anymore, so usage of this
flag is unnecessary.
Do not require MDADM_EXPERIMENTAL flag and remove obsolete information
from manual.

.B "--grow --size"
is not yet supported.
-Grow functionality (e.g. expand a number of raid devices) for Intel's
-IMSM container format has an experimental status. It is guarded by the
-.B MDADM_EXPERIMENTAL
-environment variable which must be set to '1' for a GROW command to
-succeed.
-This is for the following reasons:
-
-.IP 1.
-Intel's native IMSM check-pointing is not fully tested yet.
-This can causes IMSM incompatibility during the grow process: an array
-which is growing cannot roam between Microsoft Windows(R) and Linux
-systems.
-
-.IP 2.
-Interrupting a grow operation is not recommended, because it
-has not been fully tested for Intel's IMSM container format yet.
