Description

Is your feature request related to a problem? Please describe. Regex features are available in cudf string APIs and nvtext APIs. grep is widely used utility. It would cool to try creating cudfgrep with cudf/nvtext and document the throughput.

Describe the solution you'd like Create cudfgrep utility in our python codebase or a C++ example with libcudf APIs.

Additional context Benchmark it without GDS (most common usecase). Benchmark on GPU in PCIE, and on Grace systems with fast C2C.
