ceph-perf-pull-requests: enable llvm-toolset-10 repo for clang-10

we need clang for detecting build failures with this compiler, and for
performing static analysis.

recently, seastar started to require better C++17 compatible compiler,
and it dropped the support of C++14. so before llvm-toolset-10 is added
to RHEL8/CentOS8, we need to use our own copr repo for clang-10.
