Description (partial)

Symptom:
ip dhcp pool name string configuration accepts special-characters in the pool name string.

Conditions:
While accepting the dhcp pool-name string configuration from the operator, there is no validation of poolname string for any special characters such as tab 0x09.

When using third-party scripts or tools for generating configuration templates, sometimes the third-part scripts or tools embed special characters such as tab 0x09 into the pool-name string.

This causes confusion for operator while trying to modify or delete the DHCP pool referenced by pool-name, since pool-name consists a special character.
