OVS_COLORS environment variable is parsed to extract user-defined
preferences regarding colors (this is used to set up a color theme, not
to replace the `--color` option for activating color output).
The string should be of a format similar to LS_COLORS or GREP_COLORS,
with available colors being as follows:
* ac: action field
* dr: drop keyword
* le: learn keyword
* pm: parameters receiving attributes
* pr: keyword having parenthesis
* sp: some special keywords
* vl: lone values with no parameter name
For color whose idendifier does not appear in the string, the default
hardcoded value is used instead.
As an example, setting OVS_COLORS to the following string is equivalent
to using the default values:
OVS_COLORS="ac:01;31:dr=34:le=31:pm=36:pr=35:sp=33:vl=32"
