Context
Prowler fails in check32 when metric filter names include spaces, interpreting each single word of the name as a different metric filter name. This generates false positives from non existing metric filter names - #745
Description
To avoid this metric filter name is base64 encoded in check3x file, decoding it when its needed ( aws api calls and display messages)
