Dinesh Bhor 2562da28c6 Fix 500 if user passes name with more than 80 characters
Following apis are returning 500 error if user passes name with more
than 80 characters:
* md-tag-create
* md-tag-update
* md-object-create
* md-object-update
* md-property-create
* md-property-update

This happens because there is a discrepancy in db column length and
glance-api length check in schema validation. In database the 'name'
field for these API's is defined as of maximum 80 characters and in
schema it is defined as of maximum 255 characters. So if user passes
name with more than 80 characters and less than 255 characters
database fails to store that value and shouts with following error
which leads to 500 error to API user:

(pymysql.err.DataError) (1406, u"Data too long for column 'name' at
row 1")

Fixed this issue by changing the maximum allowed length for 'name'
from 255 to 80 in schema validation.

The metadefs schemas for 'property', 'properties', 'tag', 'tags',
'object', and 'objects' previously specified a 'name' element of maximum
255 characters. Any attempt to add a name of greater than 80 characters
in length, however, resulted in a 500 response. The schemas have been
corrected to specify a maximum length of 80 characters for the 'name'
field.
