Get values by pattern

Usage is sls key value.
You can use a glob-style pattern for the value.

• * : matches any characters: h*llo -> hllo, heeeello, etc
• ? : matches one character: h?llo -> hallo, hello, hxllo, etc
• [alphabet] : matches a character in the brackets: h[ae]llo -> hallo, hello
  
• [^e] : matches characters except those in the brackets: h[^e]llo -> hallo, hbllo, ... but hello is excluded.
  
• [a-c] : matches a character range in the brackets: h[a-c]llo -> hallo, hbllo, hcllo
• \ : to use the special characters (*?[^]) as literals, put \ in front.

• Available since Enterprise version 6.1.0.
