Execution of CLI commands with clustershell RangeSet support for decimal and hexadecimal numbers

rangeset-exec

The rangeset-exec tool written in pure Python3 can generate CLI command strings and also execute such commands with clustershell RangeSet support for decimal and hexadecimal numbers.
Range sets with hexadecimal numbers must be specified with preleading 0x or 0X.

To specify the range set to be used a placeholder must be specified in the command string with {0}.
Currently only one placeholder is supported.
