Allow relative paths for logfile configuration

[derek-shnosh]

Currently, if a relative path like ~/.meraki-cli/meraki-cli.log is defined, meraki-cli will attempt to append logging data to the current path plus the relative path. E.g., If I am in /home/ds/OneDrive, meraki-cli attempts to write to a log file at /home/ds/OneDrive/~/.meraki-cli/meraki-cli.log
