neutron install ovs failed, can`t find kernel-devel

[Wei Li]

in devstack\lib\ovs
    if is_fedora ; then
        # is_fedora covers Fedora, RHEL, CentOS, etc...
        # dash is illegal character in rpm version so replace
        # them with underscore like it is done in the kernel
        # https://github.com/torvalds/linux/blob/master/scripts/package/mkspec#L25
        KERNEL_VERSION=`echo $KERNEL_VERSION | sed -e "s/-/_/g"`

rpm name is replaced '-' by '_', but in centos7

[root@localhost ~]# uname -r
3.10.0-514.26.2.el7.x86_64
[root@localhost ~]# rpm -qa | grep kernel-devel
kernel-devel-3.10.0-514.26.2.el7.x86_64

It use '-', so can`t find it, so install failed.

Can some one bump up the priority for this bug. It is blocking devstack installation with networking-ovn.

    devstack: fix ovs install on fedora like OS

    This patch I3d0981fbe30f2436f00c200919b50aeb97491252
    resolved custom kernel version, but introduced a bug
    for the 3.x series. This patch avoids the replacement
    in the case of the 3.x series.

Fedora official kernels also use dash (and are 4.x), so I still this error with ovs rebuild:
No package kernel-devel-4.11.11_300.fc26.x86_64 available.

and package is indeed kernel-devel-4.11.11-300.fc26.x86_64 (with dash)

This issue was fixed in the openstack/neutron 11.0.0.0rc1 release candidate.
