support for variables in keyword names

[shellderp]

For example, a keyword could be defined as such: (from user guide)

Select ${animal} from list Select "${city}" "${team}" I execute "${cmd:[^"]+}" I type ${a:\d+} ${operator:[+-]} ${b:\d+} Today is ${date:\d{4}-\d{2}-\d{2}}

[shellderp]

it should be possible to replace the variable string ${...} with a regex, and for keywords that use regex, we can leave the regex there. then attempt to match

robot/running/userkeyword.py contains code for matching keywords with embedded variables
