Removes left padding for raw format

For raw format, tables had a leading space. This causes some weirdness with awk columns.
Old:
```
$ sl cci list --format=raw
 12345  dal05  something.host.com   4  4096  87.65.43.22  12.34.56.78 
 54321  sjc01  something2.host.com  1  1024  12.34.56.88  87.65.43.21 
```
New:
```
$ sl cci list --format=raw
12345  dal05  something.host.com   4  4096  87.65.43.22  12.34.56.78  
54321  sjc01  something2.host.com  1  1024  12.34.56.88  87.65.43.21  
```
