## Description 

This PR adds support for basic alias naming of Sui addresses in the
keystore. If an alias is not provided, it will automatically generate a
random name as `first-second` based on a list of predefined strings
(adjectives and precious stone gems).

## Test Plan 
Added tests to ensure new functionality works as expected. 

Manual tests:
`sui client new-address ed25519 my_alias_test / sui client new-address
ed25519`
