Thirunarayanan Balathandayuthapani 85cc6b70bd MDEV-13134 Introduce ALTER TABLE attributes ALGORITHM=NOCOPY and ALGORITHM=INSTANT

Introduced new alter algorithm type called NOCOPY & INSTANT for
inplace alter operation.

NOCOPY - Algorithm refuses any alter operation that would
rebuild the clustered index. It is a subset of INPLACE algorithm.

INSTANT - Algorithm allow any alter operation that would
modify only meta data. It is a subset of NOCOPY algorithm.

Introduce new variable called alter_algorithm. The values are
DEFAULT(0), COPY(1), INPLACE(2), NOCOPY(3), INSTANT(4)

Message to deprecate old_alter_table variable and make it alias
for alter_algorithm variable.

alter_algorithm variable for slave is always set to default.
