PT-1633 fix incorrect parsing of a variable with number + K,M,G,T

Browse Source 
This fixes bug https://jira.percona.com/browse/PT-1633

A regexp to convert numbers matches any variable ending in a number followed by character K, M, G or T, even if the variable contains other characters, fe. 'ibtmp1:12M:autoextend:max:5G'.
This fix changes the regexp so it matches only those variables that contain only a number followed by K,M,G or T
